Our friends over at TreeHugger have this great post on biking down a Peruvian mountain. It's a lot like watching the Blair Witch Project but on speed, so if you get car sick, grab your Dramamine!
This video was taken by downhill champion Alejandro Paz using an on-helmet camera and a huge set of cajónes. Don't try it at home! Check out the story at TreeHugger for even more videos: Crazy Bike Rides in Peru's Mountains (Videos).
