This skateboarder participating in the Buffalo Bill Downhill in Golden, Colorado probably didn't expect this one.

When you're skateboarding downhill at 40mph with 200 other people, you might expect to collide with another human. I'm guessing this guy will now be on the lookout for wildlife.

A mounted head camera has been useful yet again at capturing the incident. The footage shows a skateboarder ... cruising down the 1.1 mile course, which has seven turns and four hairpin turns, when you notice a deer racing them on the left-hand side. It cuts across the skateboard traffic and rams right into one of the participants in front of the skateboarder with the head-mounted camera. He is flung off his board onto the dusty side of the road.

OUCH!
