Scotjute is right with the handguns. I'm not sure about the rifle and shotgun statement, I thought that only applied to hunting. I'll have to look into that. In all honesty though, I don't pay a lot of attention when I see a truck or other vehicle with a gun rack full of guns so I never really gave it enough thought to research the law on it.
Also Gulf shores state park used to have a "no firearms" policy but it was not strictly enforced.
