"I know it�s insane to think that I could fly. But to make it possible, you truly have to believe in it � to go to a place that�s not accepted."

Said the extreme climber, Dean Potter, who would rock climb, then jump using one of those fly-squirrel-style wingsuits.

Saturday evening he died in a base jumping accident at Yosemite National Park. He and a fellow jumper were found dead below Taft Point, a 7,500 foot cliff overlooking the park�s famous valley. Their parachutes were never deployed.

So, 2 men died, with neither parachute deployed. Was that a game of chicken or some freak wind shear experience?

�I�m addicted to the heightened awareness I get when there�s a death consequence,� he told ESPN. �My vision is sharper, and I�m more sensitive to sounds, my sense of balance and the beauty all around me. A lot of my creativity comes from this nearly insane obsession. Something sparkles in my mind, and then nothing else in life matters.�
