I live in Dunkirk and havn't found anything legal in the 6 months I have had my jeep. I am hoping to get to Rausch Creek PA some time soon tho even if it's a stock jeep should still be alot of fun. Your required to have 2 or more jeeps tho and atm I don't know anyone willing to go
May is good I would consider a weekend in May. The park is almost empty on fridays.
If you're new to the park, friday is a good first day. You can check it out without a lot of other groups. Motels in Pine Grove are 7 - 8 miles away.
