It ended up beating the World Record for the biggest snowball fight EVER!!! :)
This was all filmed in a collaboration with Contour cameras! 30 percent of this video was shot on the Contour 2 and Contour Roam2 cameras! Everything else was shot on the Canon 5D Mark II and III. To watch the same event, but the video that was all shot on Contour cameras, check out the link below. (It will be up by tomorrow).
This video was filmed by Devin Graham. Parker Walbeck. The Contour Team. And a couple other shots in this came from Nav Tombros and Eric Schofhauser.
