Biker Rides Down Nearly-Vertical Dam Wall

If you were thinking of trying extreme mountain biking, this GoPro video from biker Primoz Ravnik should snap you out of it.

Ravnik strapped a camera to himself before riding his bike down the wall of a dam that is baaaaasically a vertical drop into water that must have felt like concrete when he hit the surface. Just watching the video will give you a lurch in your stomach, so we can only imagine what this guy felt like afterwards.
