By now, Aron Lee Ralston's story is familiar. Shocking, but familiar.
Hiking alone in southern Utah in 2003, he became trapped between a boulder and the canyon wall. Facing death, he amputated his own arm with a dull pocket knife to get free and find help.
Ralston turned his tale in an autobiography, "Between a Rock And a Hard Place." And his book was turned into the Oscar-nominated film "127 Hours." And Ralston launched a career as a motivational speaker.
