I lived in Georgia for 9 years and had a Georgia Firearms License, which was for concealed carry only. That was the only reason you needed a license.
On the back of the license it states; Deadly weapons at public gatherings A person is guilty of a misdemeanor when he carries to or while at a public gathering any explosive compound , firearm. or knife designed for the purpose of offense or defense. public gathering shall include but not limited to athletic or sporting events, churches or church functions, political rallies, publicly owned buildings, or establishments where alcohol beverages are sold for consumption on the premises.
So there you have it not sure if that is current, I've been back in MA for 6 years.
