These two guys completed the Dirty Dozen challenge in the mountains of Colorado. Lots of video via helmet cameras. You can really get an idea about how rough these trails can be. Desert X looks like it handled the challenge well as did the riders. Good Stuff! Some of those drop offs are pretty big. Sure would hate to have a large rock steer the bike off some of those narrow rocky trails.
