I was in Phoenix last week. Have a CO chp. Checked the gun laws. Was going into the Music Instrument Museum. As we went to enter my frau pointed to the note on the door saying NO GUNS PERSUANT TO AZ CODE ###. I said “give me the keys” and turned around to walk back to car and lock gun in safe. My frau said the guy with the family behind us smiled and said “I’d have felt safer if he had it with him.”
Sorry about the triple post
Impatient and on I 40 in the middle of nowhere.
Even when confronted with such a sign (in Arizona), if you are carrying concealed just keep it concealed and walk on in. Most they can do if they "make" you is ask you to leave and then file a trespassing complaint if you refuse.
