I actually met Dean Potter when I was backpacking Yosemite last year. He was up there doing a tight rope walk across Yosemite falls. Anyways, I swear the guy did 5 to 6 trips from the valley floor to then top of Yosemite falls IN A SINGLE DAY while carrying heavy loads of tightrope equipment. (steel cables, tension jacks, anchors, etc)
I wouldnt have believed it if I hadn't seen it myself. The guy is like freken Chuck Norris but stronger.
