there are some up in Joshua Tree National Park and some out in Gold Crown (public land) 2 good ones, I don't do much cause I'm always alone. One runs from Goldcrown into the park, the other runs from the park all the way down to around Palm springs area. there are a few short loops too, those are nice just to get out and bump along. there are also ALOT out in a designated ORV park that is up around landers, but I haven't been to that yet. I was told about a poker run going up there in October I am thinking of going to. I just have to stop back into Napa and ask the guy about it again, there is a website for it. When you gonna be out here? I'm thinking of trying to round up a bunch of Jeep people and start getting together for some trails runs and such.
