I think they do a disservice to amazing whitewater paddlers, they also teach the non-paddling public that 'this is what whitewater paddling is' which is very wrong. I very much like this video. Called 'Huck' which is an expression meaning essentially 'jumping off something' it shows the thought that goes into doing things like 70 foot waterfalls on an almost daily basis. Beautifully shot. Enjoy.
