The Atlanta Hamfest was cancelled this year, for a number of reasons including venue issues.
Atlanta has had an issue of too many chefs in the soup. There are several, depends on how you define the term, major clubs in the area. ARC, KARC, Gwinnet County, Fulton County, Stone Mountain, N. GA Radio League to mention a few. At one point these clubs were trying to put on 4 hamfests amongst themselves each year. The ATL hamfest has bounced all over, venue wise. Stone Mountain, which was held at the mountain, and it was a neat vaca to come and stay on the property at the Inn, but it has long ago moved to the Gwinnett fairgrounds. The Kennehoochee (Kennesaw-Chattahoche River, e.g. Cobb County) radio club pretty much was stable at the Cobb County Fair grounds. Consequently, too many hamfests spreading too few sponsor $ too thin. In the past ~10years, ARC and KARC have held their hamfest together but venue issues, as has happened this year, have now made it a hit/miss thing.
The Gwinnett one is still on for the fall if you live on the NE side of the area.
