Atlanta is a wonderful town to visit. There are a lot of neat things to do, great places to eat. You also have he Atlanta underground. Really enjoyed my stay.
If you are going to Columbus, N.C you have to stop by Mountain View BBQ and Deli. Awesome BBQ at great prices and always daily special. Also go to the top of White Oak Mountain and enjoy the view, its almost endless. The Blue Wall Preserve is a great hiking destination just a few miles down the road.
