I just wen mtn biking up at 7S for the first time last weekend. The trails up there are awesome and I had alot of fun. I am noob biker and bushwacker helped kick my butt the first day. See you next saturday!
One potentially interesting thing I noticed is that they have just recently widend the corkscrew trail. You know the switchbacks between goodbumps and avalanche. Its been widend to ~15 ft and graded pretty smooth too, seeded, Hmmm... I wonder why they would be working on a bike trial in october? hmm... its a mystery.
