I can neither confirm or deny that I know anyone who has carried concealed on a public school campus. But I once sat at a middle school assembly and got chatting with an older couple in front of me. They were visiting from Texas and had a grand child in the performance. Somehow the topic came up (probably comparing the "Live Free or Die" state to the "Lone Star State") and the husband declared that neither he or his wife ever went anywhere without packing and discretely patted the side of his torso. I found this quite humorous as they just declared that they were braking the law to a complete stranger and seemed to be oblivious to it. I said nothing until later that night, when I mentioned it to my wife. She rolled her eyes and exclamed "oh brother!"
