Does anyone know when they usually close the Foresthill OHV areas? Ive heard around November first, then others have said it depends on the weather; Also heard that they ride snowmobiles up there, so do they cloe all of the trails or just some? Thinking of staging at China wall this weekend and hitting the 5 and 6 trails up there. Wondering how mush longer they will be open for future trips. Any info appreciated. thanks!
