CA Dirt MTB Series race course. The bottom of Zipper has a minor re-lo not shown here. It is not bedded in yet and weather conditions have not allowed further work on it so the precise route in that small area has not been determined for the 3/18/18 race as of 3/10/18.

Still exceptionally dry and dusty, particularly the top section which was cleared a few months back by the Forest Service to create a fire break. Trail surface is gonna need some work when it rains. Check out bonc.org and sign up if you'd like to help out. Or like hoottrail on facebook.
