He is one of the coolest dudes ive ever met, incredibly talented... hes retired from kayaking these days ,but years ago he was well known for running waterfalls that no one else had ever attempted.
Heres a cool artsy short film he made back when I was closer to him, where he runs the Green river narrows ( class V) blindfolded.
