Harvest Moon is located off of I 75 north of Atlanta. It was our first stop on our trip to Illinois in 2014 and we camped there in our travel trailer. It accepts Good Sam, but you will have to call for rates. The park is well maintained and situated on a hill, but the sites are level and there is sufficient space between units. On top of the hill in another section there are quite a few long term residents.
This park is great for overnight while traveling I 75. It is dog friendly and all the utilities worked satisfactorily.
The park is a notch above average and we would use it again if on this part of I 75, however, we try to avoid Atlanta at all cost. We have experienced some terrible traffic congestion in Atlanta and try to find alternate routes.
