Yeah Potts is about the most interesting place around here thats fairly close. But there is Bobcat, Broad Run near Blacksburg, Peavine Jeeptrail up near Big Island, and there is a place just outside of Bedford thats pretty interesting, hoping to go there next weekend. For something a little further out, there is Shoe Creek, George Washington Nat'l Forest out side of Harrisonburg, and if your looking for some real hard core action there is Crozet out side of Charlottesville, we go there about once a month.
Are you on any of the local forums? If not let me know, and I will get you some links to them.
