We go wheelin' off Union Grove Road in Lithonia just down the interstate of Conyers. Its a powerline/undeveloped neighborhood. We never have issues with police. There's mud, rocks and trails. Our truck club organizes trips about every month, let me know if you head out there.

Here's a google maps link to the road it's off of.
