First of all, welcome to Ga!
There are quite a few places in N. Ga to camp especially if you like to pair your camping with wheeling!
Tray Mtn is a great place to get your feet wet here. Very simple little trail with some pretty cool campsites. A group of us will be hitting Tray on the 18 of October, we'd love for you to come out with us and we'll show you some Ga wheeling!
We're also hitting Bell Mtn and Charlie's Creek the following day after camping at Tray.
You can find a pretty good trail "guide" with rating system here:
Some good locations in the surrounding states:
Windrock/ Coal Creek
(I'm sure I've missed plenty so anyone else feel free to add to my list)
A good off-road shop near you would be AllSouth, they do a lot of jeep stuff (as most OR shops do).
There is also ACC Toyota in Scottdale (near Decatur) that specializes in Toyotas (obviously hence the name lol)
Pretty sure there is a decent amount of members in your area. Mad T (Thomas) is probably the closest I can think of off the top of my head.
Look forward to seeing you around and hope to see you on the Mid-October trip! Link to the thread here:
Lastly, if you're on FaceBook, check us out at TW Atlanta! Be sure to leave your name and TW handle so we can associate you on here with you on there lol!
