Stay at the Hiker Hostel in Dahlonega, GA.
They can slack pack you all thru GA, while spending the night in the nicest, cleanest hostel with the best breakfast that you will ever stay in.
They do this as a big part of their business. Road crossings are very frequent in GA.

Bring dramamine for the shuttle rides in the Ga mountains. Im not kidding.
