I thought I had posted about it but I can't find it at the moment. Basically, I walked about 2 feet past the security guy open carrying my .45, when I hear the "excuse me, sir." I turned and asked what he wanted, and he said "you can't take a gun in there." I told him that I could, that it was public property and hence preempted under state statute, etc. He continued to deny me, so I told him to call his supervisor. He gets on the phone, and security guy #2 asks if I have a "permit for that." I told him that I didn't need one because I was open carrying. He then proceeded to tell me that I absolutely need a permit to carry a gun, and security gal chimed in that she agreed. I told them that they were wrong, and proceeded to stand and wait while security guy #1 talks to his supervisor. Meanwhile, security guy #2 tried to placate me with the typical "Hey man, I don't think there's anything wrong with guns..." which I ignored. Finally, security guy #1 hung up the phone and told me to go ahead. I gave the ticket-taker my ticket and walked in. Other than a couple of ignorant comments I overheard, I had no further problems, even walked by several groups of sheriff's deputies.
I thought the whole thing was strange because I knew that you and others had gone and had not had any problems. I was dressed respectably (jeans/button down t-shirt), so I don't know what the deal was.
