Good overnight campgrounds:

Avoid at all costs going though middle of Atlanta between 0700 am and 7pm Monday - Friday. Use 285. Avoid the outer perimeter (285) of Atlanta during rush hour times (7-9 am and 4-7pm). Listen to 750am on your radio for traffic reports - even on weekends.
I dont know your exact route, but if you are coming from North Carolina, I suspect you will be on I85. Take I85 down the east side of I285, then to I75. Again - if you are approaching Atlanta during rush hour, go find a place to park for a while until after rush hour. It will take the same amount of time and will save you on fuel and pulling you hair out.
Trust me - I live here!
