For what it's worth I talked to a lawyer about it, since it is kind of vague, and he told me that a 51% sign pertains to all firearms.Where I am going is I can not find a law that makes it illegal to carry a rifle into a place sells alcohol for off-premise consumption, or even on premise consumption if < 51%. Is it bad google-fu on my part or does no such law exist, despite signs suggesting it does?
