Pretty serious stuff back here, and by serious I mean "seriously in need of maintenance." There is potential for some great singletrack, with some sections that aren't too overgrown/washed out to be fun.
Also, there is what appears to be someone's attempt at a freeride park in the northern end of the loops. They weren't safe to ride on, appearing to have been abandoned mid-effort. Still, though - good to see that there might be some like-minded folks out that way.
