Florida gets plenty of attention for its ludicrous people and laws. But it's not like its neighbor, Georgia, is all that far behind.
A metro Atlanta man named Jim Cooley told WXIA-TV, Atlanta that he casually went to the airport with his wife and daughter, while casually carrying his AR-15 rifle. In case you're unfamiliar, it's this thing, which is not exactly a sidearm. It's a full-out semi-automatic rifle.
Georgia state law actually allows guns to be carried in airports (and churches, restaurants, bars, and some schools). As long as weapons are not brought into TSA-controlled secure areas (because that's where it gets dangerous to carry an AR-15?), it's all peachy keen to wear your rifle like an L.L.Bean messenger bag.
