I think I might spend a weekend at Four season resort about an hour west of Pittsburgh. I think this place might be a great place for a group TW ride. This place is geared for ATV and motorcycle riding. It has over 35 miles of trails right on the property and a lot of rural areas for on road riding. What makes this place really cool is it's a really nice campground that has a lot going on like a giant swimming pool and a bunch of other stuff so you can take family members who don't ride and they can have a nice time while you ride. They have a small hotel and some cottages and cabins for non campers. I don't know if tents are allowed. They have a web site and a facebook page. I was there last fall but it was raining too much to ride but it was easy to tell that this place was all about off road riding.
