The only places I can't legally carry are courthouses and places that serve alcohol here in AL. I'll carry everywhere else. If a store has a sign on the door I figure what they don't know won't hurt them. Of course I've never seen a store here that forbid carry in it. I don't go to either of the above illegal places to carry unless I know I'm going there. Not a problem for me here in AL i guess.
