The best place is Rausch Creek in PA. It is just north of Harrisburg and has something for everyone. Another option now is RedCloud Offroad in NoVa. It is more tame than Rausch but can still be fun. Rausch is open every weekend but RedCloud is only open on specific weekends but there are a lot of them quite honestly. There is also Big Dogs a bit farther down in Va but i have not been there yet so i cant really comment on the trails there.
