We show a lot of crazy extreme sports videos around these parts, but nothing compares to last night's "60 Minutes" story on Alex Honnold. The subject of a doc*mentary last year called "Alone on the Wall," Honnold is the world's best — and perhaps most insane — free solo climb. He scales sheer, steep rock faces as if he were Spiderman, without the aid of ropes or any other safety support. One slip on a wet rock, one wrong move, or one sudden weakening of his fingers, and he'd surely fall to his death. This is seriously the most-stomach churning 13-minute video I've ever seen. It's below.
