In the Dukes of Hazzard, the general feeling you get when you hear them talk about “Capital City” is a reference to Atlanta, but outdoor scenes show California mountains, not Georgia (which is a constant source of irritation).
But there are also references to Atlanta, and in a very early episode (maybe the pilot) Bo & Luke went to Atlanta. Maybe suggesting Atlanta is the closest major city, but they're across the state line in "Capital City's" state?
The first dozen or so episodes were shot on location in Georgia, and I've always thought the series was set in Georgia. As far as the Alabama road sign, continuity was never a strong suit on the show. The California mountains in Dukes don't bother me as much as the grassy lawns shown on CSI. (Las Vegas is in the desert, people don't have grass lawns.)
These threads are fun.
