Adrenaline Junkies

I am an adrenaline junky, but I've now fallen enough times to know my limitations and develop an aversion to chronic pain.  On the other hand, I really enjoy the video clips of people with less fear than I have...  These are pretty amazing to watch in full screen mode.

This guy makes a really cool move at 2:05 to scrub off some speed before entering a tight turn.

An oldie, but still pretty intense.

How about some raw speed at very close quarters?
