It varies from state to state, but carrying on the premisis of a place with a posted "correct" no carry sign, you can be charged with criminal tresspassing and will most likely loose your permit to carry. Not to mention what you could be charged with if using the gun. While we carry for our protection its a little odd to break the law that may send you to jail....protection comes in many different forms. We could have the protect yourself and deal later debate, but bottom line is you need to know the law and what your up against if you break it. In Texas at least, you get caught breaking any of the "little" carry laws, you loose your permit....period.
