Overnight Rv park on I-75 either south or north of Atlanta

Look at your map and find rt 441, it is east of Atlanta (goes thru Athens) and is a much better road than I-75. It really is not that much slower and there are campgrounds all along it and nice little towns to stop and stretch the legs. I took that way this past march and now I will never ever take 75 again. So much less stressful than the expressway.
