I think this whole thing is a little silly, and very dangerous, but none the less, the limits were pushed a little further in Whitewater Sport for new heights in successful waterfalls run in a kayak.

Regardless it was a breathtaking descent and I had front row seats having rappelled off the ledge to run safety and snap a few photos. Here is an article about it in the Oregonian.
