00:04On Ask This Old House, our experts travel across the country to answer questions about your house.
00:17Today, Lee gives a driveway a coastal makeover.
00:21Look at that. Nice.
00:23Then, we challenge our crew with a game of what is it?
00:27OK, boys, it has spiral wires at the bottom and it spins.
00:33And are you concerned with radon levels in your home?
00:37Ross helps a homeowner test and mitigate the problem.
00:41Coming up next on Ask This Old House.
00:47Today, I'm on my way to replace a gravel driveway with a seashell driveway.
00:52This house is located on the coast of Massachusetts.
00:57This homeowner is looking for that classic Cape look.
01:00And the seashell driveway is a big part of it.
01:04I love them. I think they're really nautical and really beautiful to look at.
01:10When you line them with cobblestones or some type of edging on them, they look really sharp.
01:15Seashell driveways are very popular in coastal communities because of the product.
01:20You know, you have the fishing industry and so they're recycling the shells.
01:25It's going to be a great transformation.
01:27I'm excited to do this project.
01:29It's going to look really nice.
01:32Hey, Lee.
01:33Hi, Patrick. How are you?
01:34Great, great. Good to meet you.
01:35Thank you. Nice to meet you, too.
01:36So I got an email from you and something about a driveway.
01:40Yeah, yeah. Living in coastal Massachusetts, I see a lot of seashell driveways.
01:43Okay. I love the look.
01:44Okay. I would love to have one.
01:45All right. Seashells? Great. I love them.
01:48I have one. They're beautiful to look at.
01:50When you pull in the driveway, it's nice.
01:51Any drawbacks?
01:52Drawbacks? Shovel and snow.
01:54Yeah.
01:54Maybe a little rough on the feet.
01:55Mm-hmm. That's right. I already have the gravel driveways.
01:58So we're good.
01:58Yeah.
01:59All right. So let's talk about the layout.
02:01What are you thinking?
02:02So I was wondering if we could square this corner off.
02:04Okay.
02:05Are you going to be okay going all the way back into the flower bed?
02:07No, I think that would get too close to the flower bed.
02:09I agree. Okay.
02:10I was actually wondering if we could shorten it a little bit.
02:13Okay.
02:14I don't need all this length.
02:15All right. Perfect.
02:15So how if we go right back to here to the separate?
02:17That's perfect.
02:18That would look nice. It would be a nice straight line.
02:19Yeah.
02:20And then coming into this area here, we might have to be eliminating that one step.
02:24You okay with that?
02:24No, that's fine.
02:25Okay. Great.
02:26All right. So from there, all the way back over to this area, what are you thinking over here?
02:30I was actually wondering if we could widen it a little bit.
02:33Okay.
02:33Okay.
02:33I have two cars.
02:35Sure.
02:35They fit as is, but just barely.
02:38Okay.
02:38Let's not encroach too much on the slope because we've got a slope.
02:41Okay.
02:41Let's do about, I don't know, what do you think?
02:43How about another three feet?
02:45Three feet is perfect.
02:45Is that feeling good?
02:46Yeah, three feet is perfect.
02:47How much material do we need?
02:48So I like to do length times width times depth.
02:52Okay.
02:53But in a new setting, they recommend three inches of depth of the shells.
02:58So we're going to do some measurements.
02:59Can I help you measure?
03:00Sure.
03:00Let's go from at the bottom right where you're standing pretty much.
03:03So we're roughly 30 feet.
03:05And let's go wide.
03:07So 30 by 20.
03:08All right.
03:09So I'm going to call the supply company and give them the measurements that we have.
03:12So we're 30 by 20 by three inches deep.
03:16Awesome.
03:20Okay, Patrick.
03:21So now we've got to gather up all the stone.
03:23What do you think about the stone?
03:24Want me to haul it out of here?
03:25Do you want to keep it?
03:26What do you think?
03:27There's actually a few projects I could use it for.
03:28Good idea.
03:29Okay.
03:29So we'll repurpose it.
03:30It looks like a lot of work.
03:32Yeah.
03:32How are we doing this?
03:33Well, the old fashioned way we could rake it all up in small piles, but I have this tool
03:37over here where you can rent and it's a power broom.
03:40This thing right here?
03:41Yes.
03:41It looks amazing.
03:42It's similar to like a weed whacker, similar style, but it has a broom on it.
03:45And this will help us gather up all the stones.
03:48Okay.
03:48Make sure with the power tools, we always have air protection.
03:51Okay.
03:52And we have our safety glasses.
03:54Perfect.
03:54Right here.
03:55I'll show you how to start it up.
03:57Turn it on.
04:06I'll follow your lead.
04:07I'll follow me, okay?
04:21We've got some piles.
04:22Now we've got to put them in the wheelbarrow.
04:24Do the best we can.
04:25Take your time.
04:27How deep do you want to go?
04:28I don't want to get too deep.
04:29We're getting into the sand level.
04:31I want to stay in the hard level.
04:33One layer of stone.
04:34Correct.
04:34The hard pack.
04:35That look there.
04:36That's perfect.
04:36We're in good shape.
04:38And the lines are drawn out.
04:40And that's where we're going to expand the driveway.
04:42And to do that, let's take out these stone edgings.
04:45So we've got this grub ax.
04:46Okay.
04:47It's got a pick on one end.
04:48So I'm going to go behind it.
04:50And plop it up.
04:52Okay.
04:53See that?
04:54They come right up.
04:55Coming out pretty good.
04:56Okay.
04:56Yeah.
05:05Next job, we're going to do a side cut.
05:07I brought a side cutter.
05:08A machine that will slice underneath the grass.
05:10We'll take that out nice.
05:13Okay, Patrick.
05:14We're going to remove the soil.
05:17So this is a Portuguese grub hoe we're going to use.
05:22And just pull it up like that.
05:24Okay.
05:24Just start here and move along the line?
05:26Yes.
05:26That'd be great.
05:27We're not going down too deep.
05:28Yeah.
05:28Just on the surface.
05:29You know what I mean?
05:29Don't be afraid of it.
05:30Pull it back.
05:31There you go.
05:32There we go.
05:33Okay.
05:33I see.
05:34Okay.
05:35Nice.
05:36You make it look a lot easier.
05:3930 years in the business.
05:40There you go.
05:41Perfect.
05:42You want the old man to finish up?
05:43Unless I'm messing it up hard.
05:45No, you're doing a good job.
05:46The old man can finish it up though.
05:47You know what I mean?
05:52It's too bad.
05:52You don't have some machine that does this.
05:54I know, right?
05:57I think we're in good shape with the edging.
05:59But I know the shells are on the way.
06:01So let's hold off.
06:02Okay.
06:04Look at that.
06:05Nice.
06:08Okay.
06:09We got our shells delivered.
06:10What do you think?
06:11Beautiful.
06:11Smells like the ocean.
06:12But that's going to go away in a couple of days.
06:14Okay.
06:14All right.
06:14It looks like a local guy down here delivered it.
06:16So that's nice.
06:17Yeah.
06:17But you got a good variety.
06:18We got some clams.
06:19This is a quahog it looks like.
06:20This looks like a scallop.
06:22What do you got over there?
06:23A clam?
06:24That looks like a clam.
06:24Yeah.
06:25Yeah.
06:25So over time, this is going to bleach out in the sun.
06:27Beautiful.
06:28All right.
06:28So let's get back to putting some edging down, huh?
06:31So now we're going to put the plumb line down.
06:37And I'm also going to want to use the three quarter inch stone that came out of the driveway
06:40earlier.
06:41We'll put that down and then we'll tamp it down by hand.
06:45Let's get a few in.
06:46See what it looks like.
06:48That looks a good fit.
06:49Is that it?
06:50Yep.
06:50Perfect.
06:51We'll get in there.
06:52We'll give it a little tap.
06:56Last one.
06:57We got enough too.
06:59Oh, fit.
07:00Nice fit.
07:03That's pretty good.
07:04Yes.
07:05Beautiful.
07:05Okay.
07:06Now we got to spread some seashells.
07:08So what I'm going to do is just cast it out.
07:13Am I going too much with the spread here?
07:15Nope.
07:15That's pretty good.
07:16Okay.
07:17Just get a good even coverage.
07:27Okay, Patrick.
07:27What do you think?
07:28I think it looks great late.
07:29We can see the light at the end of the tunnel.
07:31So now we got the last step we got to do is we got to compact it.
07:33Okay.
07:34And I'm going to give you the blower.
07:35Do me a favor.
07:35Just like clean up a little bit of the edges.
07:39What do you think?
07:40I think it looks great.
07:41Not bad.
07:42Thank you very much.
07:42Good day's work.
07:43Yeah.
07:43So homework, I need you to backfill it with some loom all the way around the block.
07:47Okay.
07:47Just a little bit of loom on the backside.
07:49And just get a little pile of this stuff.
07:50Maybe a yard or something like that.
07:52Just for touch up.
07:53You know what I mean?
07:54Okay.
07:54Just to fill in where I need it.
07:55Wherever you think you need it.
07:56Okay.
07:56Good luck with it.
07:57Thank you very much.
07:57Nice to meet you.
07:58You too.
08:11Okay, boys.
08:12It's shaped like a broom, has spiral wires at the bottom, and it spins.
08:18What is it?
08:19I know that one.
08:19Shaped like a broom?
08:19Somebody's never used a broom.
08:21That's not a broom.
08:22Tommy, you and I were just talking about this.
08:23I know we're starting to shop for nursing homes.
08:25I know you've been looking.
08:27Starting to?
08:27Yeah.
08:28And the one I was at the other day, it was unbelievable.
08:30You know, they get bingo at three.
08:31Yeah.
08:32Jeopardy at five.
08:33And you want to come down.
08:34And sometimes you can't make the three o'clock bingo.
08:36All right.
08:37Well, it is portable bingo.
08:39Is there any number?
08:40Yeah.
08:42It's not what it is.
08:43Oh, my God.
08:44My hand's stuck.
08:45Very creative.
08:46They're not even close.
08:47This is massager.
08:48A back massager.
08:49Turn around, Sonny.
08:50Oh, my.
08:50No, no, no.
08:52Come on.
08:52We're all on the team.
08:54You're gonna love this.
08:55Look at that.
08:55How's that feel, huh?
08:58Get the back of your neck like that.
08:59Oh, wash the coif.
09:00Wash a little lower.
09:01Come around this way.
09:02Oh.
09:03The handle's not long enough for that.
09:05Okay, okay.
09:06Long way around.
09:07All right, wake up.
09:08Wrap it up.
09:08Wake up.
09:09Wake up.
09:09Come on.
09:09Stop.
09:10That's it.
09:11That's exactly what it is.
09:12Very nice.
09:13But not what it is.
09:15I don't know what you all do to walk your hamster.
09:18What?
09:19But this is my hamster walker.
09:22What do you do?
09:22Harry, my hamster, used to be on the wheel just looking at the same thing all day long.
09:26That's what they do.
09:26And that seemed a little cruel.
09:27Yeah.
09:28So now, I put them in and I take them out and we walk and I send them forward and
09:32backwards
09:32while I walk.
09:33He's lost a lot of weight.
09:35Very good exercise.
09:35The whole neighborhood.
09:36Sprint.
09:37You go in the neighborhood.
09:39Those little legs.
09:39Those little legs.
09:40Sprint.
09:40Okay, okay.
09:41You're the closest because you had it touching the ground.
09:44Oh, that's it?
09:45What it actually does is it picks up nuts.
09:48Hamster nuts?
09:49It could be hamster nuts, the shrapnel, but acorns.
09:53Acorns.
09:53Okay.
09:54All you do is wheel it right over.
09:57Look at that.
09:58Look at that.
09:58It's fun for all ages, young and old.
10:02Any kind of nuts?
10:03Like macadamia?
10:03You can even do it in your wheelchair.
10:04How about chestnuts?
10:06Chestnuts.
10:07Oh, look at that.
10:08And then you have your collection and there you go.
10:11Let me just see right here.
10:14E7.
10:14Oh, bingo!
10:19I'm headed to a home that has elevated radon levels.
10:22Radon is a naturally occurring radioactive gas
10:25formed from a byproduct of uranium,
10:27which is found in rocks and soil beneath our feet.
10:30That radon gas can rise up and enter through the slab,
10:33foundation wall, through a water pipe or a sump pump basin.
10:37And if the concentration rises too high,
10:39it can become problematic because it's the number one cause
10:43of lung cancer for non-smokers.
10:45Now the only way to test is actually to monitor.
10:48You can't detect it with your nose.
10:49It's invisible.
10:50It's odorless.
10:50And in this case, the homeowner installed a monitoring system.
10:53So we know that they have an elevated radon level.
10:55So we've got to install an active system to solve their radon problems.
10:58I'm headed to the homeowner's house right now to take a look.
11:05You must be Vincent.
11:06I am, Ross.
11:07Yeah, nice to meet you.
11:08Nice to meet you.
11:10So you wrote in about elevated radon levels.
11:12So tell me the backstory and how you came to that.
11:14I did.
11:15So I just recently inherited the house from my grandparents.
11:18Okay.
11:19And I would say about five years ago, their dog died of lung cancer.
11:23Oh, wow.
11:24And I learned that's pretty rare, especially since the dog wasn't among smokers.
11:29Hmm.
11:29So I did a little research, found out about radon,
11:32and found out that radon does cause lung cancer.
11:34Yeah, radon's actually the number one cause of lung cancer for non-smokers.
11:39And then pets are, you know, at a higher risk because of the fast respiratory rate.
11:43They're indoors for many, you know, for long periods of time.
11:45And radon gas likes to settle in the basement,
11:47where a lot of times pets spend a long period of time as well.
11:50Yeah, so now I'm kind of worried about myself, but also my new dog, Daisy,
11:53who's running around here somewhere.
11:55So I did a little bit of research, and I've noticed that the neighbors over there
11:58have their own radon mitigation system.
12:00Yeah, I can see that.
12:01The white pipe coat on the side.
12:02If they have it, I mean, we definitely have an issue.
12:05And so I bought a radon test and noticed, like, very high levels of radon.
12:09You do? So you already have a radon monitor?
12:11I do.
12:11Okay. So can we take a look at that?
12:13Yeah, sure. It's right inside.
12:14Awesome.
12:16All right, Russ. I've got the radon monitor right here.
12:20Well, you're already one step ahead.
12:21What we usually like to do is test with a continuous monitor like that
12:24to just see what the radon levels are over time.
12:27So how long has that been installed?
12:28This has been here for about three months, and I have some of the data right here.
12:32So this is like my three-month average, and we're looking at like a 12.7.
12:36That's picocuries per liter, and the EPA recommends an action level of four.
12:41So you're about three times the EPA limit on the average right now.
12:44Wow.
12:45The other thing to point out here is that if you look at the one-day average, you can see
12:49over the course of this last day,
12:51it literally fluctuated from three to 15.
12:55So a lot of people think that radon levels are static, like you do a short-term test and that's
12:59it.
12:59But this is why we stress continuous monitoring is that it's very dynamic. It's always changing.
13:03You add cold weather outside. You add in, you know, exhaust fans like ventilation systems,
13:10bath exhaust, dryer venting. You add in high groundwater like with a lot of rain.
13:14You add wind. You add those things. It's going to change, right?
13:17It's going to create more chances for radon gas to get pulled into the basement.
13:20Okay.
13:21So with this, we recommend action for sure.
13:24And what goes into that?
13:26So that would be a radon mitigation system, and we call that an active sub-slab depressurization system.
13:33Okay.
13:33It's a fancy way of saying we're going to take a white PVC pipe.
13:36We're going to drill a hole in the slab, stick a pipe down through it.
13:39We're then going to bring that pipe up, bring it out through the side of the building, through the rim
13:43joists,
13:44and bring it up the side of the building.
13:45We're going to put a fan on it so that it's active, meaning it's operational,
13:50and that's going to create a suction underneath the slab.
13:53So we're giving an escape path for that radon to basically get pulled from below the slab
13:58and run it out through the roof, never having a chance for it to actually enter the basement.
14:03Okay.
14:03This can be really easy to do, or it can be really complicated to do, depending on the age of
14:06the house.
14:07I assume the house is pretty old, but how old is it?
14:09Yeah, it's about 100 years old.
14:10Okay.
14:11So with an older house like this, we probably have compacted dirt and soil underneath our slab.
14:17In a new house, we'd have a nice gravel base.
14:19So when we put that fan down in a new home, it's usually pretty easy to create that suction
14:23throughout the entire concrete slab because you have a gravel base that allows all that radon gas to move.
14:29Okay.
14:29In an older house, it might be a little bit more complicated because of the compacted earth.
14:32We don't have that kind of passageway.
14:34You know, we call that pressure-fill extension.
14:36We don't have enough air flow underneath the slab.
14:38So we're going to do some tests to verify that.
14:40Okay.
14:40Other thing is well water.
14:42Are you on a well or a domestic water well from a town?
14:45There's no well water.
14:46No well.
14:47Okay, great.
14:47That would be the other thing.
14:48It's completely separate, but radon gas can enter through the well water on a well system.
14:53But you don't have that issue, so we don't have to worry about that.
14:55Okay.
14:56Next thing is we're going to call a certified radon mitigation company to come help us out.
14:59I already did that, and so Chris should be here.
15:02I'm going to go meet him outside and we'll get started.
15:03All right.
15:04Thank you, Russ.
15:04All right.
15:04Cool.
15:05Thanks.
15:06All right.
15:07Vincent.
15:08Meet Chris.
15:09Chris, Vincent.
15:11Hey, nice to meet you.
15:11Yeah.
15:12He's going to help us with the radon mitigation system, and so we'll start with that visual
15:15inspection.
15:16Okay.
15:16All right.
15:16Sounds good.
15:18So what we're ultimately doing here is looking for any openings in the slab.
15:22So I'm going to have to put some mortar right here.
15:26It looks like there's another opening over here.
15:29So what we're trying to do is because we want to seal that up so that we can, when we
15:33create that suction beneath the slab, then we're pulling the radon gas beneath the slab
15:35and not from the basement space.
15:38Okay.
15:38It looks like there's a clean-out over here that I'll have to seal.
15:43Put a cover and seal with some caulking.
15:46Yep.
15:46So we'll seal up that corner clean-out.
15:49Still give you access if you need to access it, but at least it's going to be sealed up
15:52so that radon can't come up through that opening.
15:54Okay.
15:55There.
15:55The other thing we're going to do is grab samplers.
15:58So what those are, in the four corners, Chris is going to set up a very accurate radon
16:03monitor and we're going to leave the house for 30 minutes.
16:05We're going to watch the radon levels in the four corners to see how the radon moves through
16:10the basement.
16:11Is it more in this corner?
16:13Is it more in that corner?
16:14Is it more in that corner?
16:14Where is it?
16:15Is it equally dispersed?
16:16We're trying to figure out how that radon flows through the basement.
16:19Okay.
16:20And that's how you determine which access point to put the mitigation system in.
16:24That's exactly right.
16:25Yeah.
16:25The hottest spot.
16:26I mean, the part that has the highest radon level is ideally where we create that suction
16:30point and drill that hole through the slab.
16:32Yep.
16:33So we've got the results of the grab samples.
16:36So let me show you that.
16:38So we were at between five and seven in all of the other three corners.
16:43But this corner was almost 22.
16:46Wow.
16:47So this was definitely the hottest radon level.
16:50So this would be the best place to create that suction point to basically pull that radon
16:55gas and let it get out of the building.
16:57Okay.
16:58So Chris, what do you think for location-wise?
17:00Yeah.
17:01I think a good place to go out would be up in between these two choists.
17:06So if we could move this, we might be able to drill a hole right here if that's okay.
17:10Yeah, absolutely.
17:10Let's get that out of the way.
17:11Okay.
17:12So we'll do a hole here.
17:13And we're also going to drill three other holes at the other three corners.
17:18So when we hook up a shop vac, we can actually measure the pressure between this hole and
17:22the other three corners of the basement.
17:24So we can understand how much airflow we have underneath the slab.
17:31Okay.
17:31So we've got the four one-inch holes in the four different areas of the basement.
17:35We've got Chris with the shop vac over there at the main suction point.
17:38And what we're looking for is airflow pathways from the holes that we've drilled back to the
17:42main hole.
17:43Okay.
17:43So the first thing I do for visual representation is smoke.
17:47So this is theatrical fog.
17:48And so without the fan running, we can just see that nothing's really going down the hole.
17:53Yeah.
17:53But now, Chris, if you can turn on that shop vac, he's pulling a negative pressure.
17:59Watch this.
18:02See it?
18:02Wow.
18:03We're good.
18:04Yep.
18:06So we're proving that we have an air pathway from this hole back to that hole when you create
18:10that suction.
18:11Okay.
18:12So that's visual.
18:12And now we can also do it with pressure, right?
18:15So this is the one that we see the most.
18:16This is called a manometer.
18:17What it is, is a pressure gauge that measures the differential of pressure between this tube
18:24and this opening right here.
18:25So we're measuring the pressure below the slab with reference to this basement space.
18:30Okay.
18:31So we can see that we're at a very, very low level.
18:33Yep.
18:34All right.
18:34Now, if we turn the shop vac on, Chris, if you turn that on for us.
18:40Now, watch it go up.
18:42Negative 0.02, right?
18:450.18.
18:45So we have that negative pressure now, again, proving that we have an air pathway underneath.
18:50Okay.
18:50All right.
18:51So we put a fan there.
18:52We're going to create suction here.
18:53We're going to get that radon gas out.
18:55Great.
18:55Awesome.
18:57Okay.
18:58So that's great for this hole.
18:59Next up, we do the same test of the other two holes.
19:01Make sure we have an air pathway back to the fan and then we can let Chris get to work.
19:05Okay.
19:05Great.
19:05Sounds good.
19:09Now that Chris has made a four and a half inch hole opening, we can remove the material underneath
19:14that opening to make sure that we have a proper reservoir or sump to allow that radon gas
19:19to collect to be pulled up to the suction port.
19:21Now we'll use a host of different fittings to allow that four inch PVC pipe to transition
19:26to three inch to then run up the wall and out to the rim joists.
19:42With that made, we can have a fan on the exterior of the building and have Heath the electrician
19:47wire up that fan.
19:48And we're in business.
19:55All right, Heath.
19:57Perfect timing.
19:57How are you, Ross?
19:58We ran the radon fan.
19:59The mitigation system is in.
20:01We are ready for power.
20:02Yeah.
20:02Look at the easy part.
20:03There's a little bit of power over here and we'll be good.
20:04So looking at the basement, it looks like it's pretty simple to get to.
20:07All we have to do is install this weatherproof disconnect outside.
20:10It's our service switch.
20:11So it's just simply this on and off.
20:13And all that's involved in this is really the plastic housing.
20:15We're going to have a piece of condo go up to standard switch.
20:18Yep.
20:19But you can see inside when you put that on, it just simply toggles it on and off.
20:23Nice.
20:23And with the cover, we have the option to lock it on or off as well.
20:26So we'll keep this thing running.
20:27Yeah.
20:27So keep it on all the time.
20:28But if you need to service it, it's nice to kill it.
20:30That's it.
20:30All right.
20:31Cool.
20:31We'll go see Chris back inside.
20:56All right, Vincent, the radon mitigation system is in.
20:59It's operational.
21:00The fan is moving air.
21:01Great.
21:02So just a couple of things.
21:04This is a manometer.
21:06And as long as the fluid is higher here than it is here and doesn't look like it's even,
21:12like that, then that means the fan is working.
21:16Okay.
21:17So if the fan ever stops, that will even out at zero.
21:20That's a good visual indicator just to make sure it's working.
21:22Yeah.
21:22Yep.
21:24Also, this alarm will go off.
21:26Once a minute, it'll beep to let you know the fan's not working.
21:30Okay.
21:30All our information's on here.
21:32Okay.
21:32So if that ever stops, just feel free to give us a call.
21:35I will.
21:36So how long does the fan last for?
21:39On average, the fan will last for about 10 years.
21:41Mm-hmm.
21:42There's a five-year warranty on the fan.
21:44Oh, okay.
21:45So if it ever dies, then just give us a call and we'll come out and swap it out.
21:48Okay, great.
21:49So also over here, we have a continuous radon monitor.
21:53Mm-hmm.
21:54So we're going to leave that for a few days.
21:56Let that run to make sure that the levels stay below four.
22:00Okay.
22:00It's important to test every couple of years.
22:06So after to make sure the system's still working.
22:08Mm-hmm.
22:09Okay.
22:09What's great about that, you already have a continuous monitor?
22:12Right.
22:12So you can just leave that in place and then that way you always have continuous monitoring
22:15Okay.
22:16Every minute forever.
22:17Okay.
22:18Yep.
22:19So is there any other questions?
22:20No.
22:20Thank you guys so much.
22:22All right.
22:22I really appreciate it.
22:22Daisy and I, thank you.
22:24Awesome.
22:24Awesome.
22:25Thank you, Chris.
22:26Yeah.
22:26All right.
22:26Take care.
22:27You too.
