This weekend, Mat Olson, a professional BMX stunt rider rode his bike over the arches at the West 7th Street Bridge in Fort Worth, Texas. And yes, there's video to prove it. Mat, who did the stunt illegally, rode the six 24-foot-high, five-foot wide arches, hoping to get enough publicity to get in this year's X Games. The Fort Worth authorities aren't exactly happy with the stunt either. Police gave Mat a stern talking to, and measures have already been made to keep any similar stunts from happening in the future.
