I am going to try Durhamtown Plantation up in GA this weekend. They are suppose to have 4,000 acres of trails with fishing, camping, and pistol and rifle ranges. They also rent ATVs and Gear, and have a proshop on site. I didn't see anything about side x sides on thier site, so I called and they said that side x sides are welcome. The person on the phone told me that they also have a 4x4 park for trucks and jeeps, with mud, trails, and rock crawling. This place is located east of Atlanta, but I haven't looked up the directions yet.
