I admit, I'm a fan of extreme sports. They sure as heck are more fun to watch than traditional sports like Basketball (with the exception of that Pacers v Pistons BRAWL) since the only requirement of a base jump is 1000 feet or more AND a parachute. That's it. There's an added uncertainty because you're at the mercy of much shorter spaces (as compared to jumping from a plane at 3000 feet).
Anyway, this video shows that there is another ADDED component... CLEARANCE. Check out the cliff face to see what I mean
