 Who knew we had loam in California?

 Not to many places you can find a fast downhill loamy section in this area. Awesome fun and highly recommend it if you have the endurance to get there.

 This part of Grouse was a blast it had speed, rocks, flow, loam, fun logs to boost off of. It was a nice degree of difficulty where could enjoy it and not feel you might die Smile Enjoy this section because when you come to the Double Black Section of Grouse things are going to get a lot more hectic. This part of the trail starts at 1:01 - 1:35 of the video Entitled "Grouse Ridge" posted under the video tab. Its true further down the trail logging has begun and its all torn up and hard to find the trail, we found it with a bit of searching, if you use common sense and your instinct on where you think it would go you shall find it. Its off to the left.

 BONC fixed up that part of the trail that got torn up by the loggers. I helped out a bit and got to ride it. It's great and I can't wait to do that again.
