Open carry is not illegal here, although if on somebody’s private property or quasi-private such as a mall you may be asked to leave and come back without.

They post signs here, covering both concealed and open carry. If you choose to ignore them and get caught, it's bad news.

Some places are insistent on allowing no firearms. The US Post Office is one, and the Federal Building, and bars. Bars don’t like firearms in there, so most incidents are out in the parking lot.
