Well, the only place I have seen that is in National Parks, and yes, kind of the same as government buildings. The Fed's just don't like us carrying sometimes Now, there are various buildings and business, etc, that will say "no firearms". But, all they can do is ask you to leave. You refuse, then it's trespassing. A business can set its own rules, but it still is not illegal to carry there, if that makes sense. I do still carry in those situations.
