I am not sure on this topic, but I would also like to know. I am new to OC but have a CC permit. I CC carry everywhere! If you have a sign it makes no difference to me what so ever. All you can do if you find out I have a firearm is ask me to leave. If I comply with your request its over. If I don’t leave then you can get me for trespassing.. These signs are ridiculous! I am sure I am not the only person that would rather have the gun when needed then say Wait a minute let me go to my car and get my gun, you stay right there and then Ill come back and shoot you..
