This is a first-person video of some guy jetskiing through a water-filled canyon on Lake Powell. It looks wild, especially since the water is so calm and its reflection so clear that it looks like the jetski is hovering. Me? I would have crashed into a wall and drowned on the first turn because I was too cocky to wear a life vest. PROTIP: always wear a life vest. Unless you're jumping out of a plane, then always wear a backpack. "You mean a parachute?" No, just a backpack.
Keep going for the video.
Thanks to Ben R, for being man enough to admit he still wears water wings in the pool.
