The wife and I have been ever since before we even got the permits (which are mostly redundant in AZ), but my experience the other day led me, and the wife, to a full-out open carry walkaround at the WallyWorld. Only noticed 1 lady eyeing the wife's hip, but then went back to her cellphone conversation. No real difference in anyone's behavior. I always smile and nod when someone makes eye contact anyway, and polite "excuse me's" when I'm in someone's path. Cashier didn't seem to notice or care. Mine was actually in an IWB AG holster, but the shirt was tucked behind, so the grip was clearly visible. The wife's was OWB Don Hume lefty. We were prob there about 30 min inside, never a single issue.
