Check out this famous video of Dan Osman, a Japanese-American outdoor adventurist who like to run up 400+ feet tall crags &mdash like this one at Lover's Leap near South Lake Tahoe &mdash without any protection. Most of the time, climbing this rock requires a lot of hardware &mdash nuts, camalots, quickdraws, a rope, a belay device &mdash but when you're Dan Osman, all you need is a lot of balls. Osman was also an avid free-jumper &mdash he liked to jump off of cliffs with a normal rope (not the elastic kind that softens your fall like in bungee jumping) that would place him just inches off the ground. Sadly, but not too surprisingly, Osman died in Yosemite at the age of 35 when a rope failed him.
