Normeller, we will be staying around Memorial Weekend. Cartersville is a way out, but it isn't too far for our meeting with family from Atlanta. We figured the closer we are to Atlanta over that holiday, the harder it will be to find a campground with larger sites for a family visit. I would think we would need reservations given it is a holiday, unless you think that Thursday before that weekend would be early enough to get a campsite. That one you are talking about would mean a longer drive for us since we will be coming from the NW-Chattanooga area.
Thank you for your reply!
