Butt clenching is a tiresome endeavor here is Curtis doing some of those trails http://youtu.be/fdCj4SHQaME
Looks like partially First Crack, and partially Samurai? Nice riding! Those trails are much steeper and more difficult than they appear on video. Curtis makes them look way too easy.
Sounds like you shared a tent with Donny I was going to say nice run but Curtis made you look like you were riding that vintage bike you're trying to restore =)
