Nothing as exciting as some of the previous posts, but the closest to work is the Martin Luther King Center historical district (BRAG's Bike Atlanta fest met there last year). It's a great place to visit. Also President Carter's library, Margaret Mitchell's house, Centennial Park from '96 Olympics. There are also civil war battlefields and cemeteries - they are pretty cool. New attractions include the World of Coke (interesting for the history of Coke and to taste all the flavors sold around the world) and the Georgia Aquarium.
