Here in the 49th and final state to allow concealed carry of guns, the law is clear.

If the owner posts a sign it must be 5"x7" minimum, and can say just about anything as long as it conveys the idea that you shouldn't have anything that could be construed as a weapon.... So just about any sign will work.

The punishment for ignoring such a sign is a fine of $200.

I know I'm not turning around and walking away in most cases. I am concealing and nobody knows.

I DO believe any business that REMOVES my right to defend myself should be responsible for my protection while in their establishment.
