Dude, scary stuff...I'm no doctor by any means, but, being that this guy is your buddy you should seriously recommend he see a doc - no doubt he's suffered a concussion.

First time I ever rode Sunderbruch, I took a very nasty spill in the exact same spot - too much speed and I didn't know how to handle it, grabbed a fist full of brakes and went shoulder first into a tree, rolled head over heels across the trail, and went head first into another tree...scary stuff.

Glad to hear everyone's ok!
