Sometimes you have to wonder what motivates people to do stupid things....like go over a 90-foot waterfall in a kayak! They will tell you it's the thrill and rush that accompanies such a dumba..,I mean dangerous stunt. That is exactly what Isaac Levinson and two other kayakers did at Noccalula Falls in Alabama recently when they strapped on helmet-cams, paddled down stream and went over the falls. All three lived to tell the story which is absolutely amazing. You can see their exploit below. Enjoy, but don't get any bright ideas about doing this yourself.
