This is a video of David Salmon riding a private waterslide at a residence in Austin, Texas when he flies out of the slide and 10 feet down to rocks below. Pfft, and I thought you were a Salmon — you should have just swam back up the slide! David had to go to the hospital with a broken arm and several ribs, but is otherwise fine except for his incredible fear of waterslides.
