I was in KC MO from 7-25 through 7-31 and stayed in the Marriott Courtyard Suites. One morning I saw a youngish man OCing in the breakfast line. I was with a group and could not break away to introduce myself and find out if he was LE or not. Days later, I spotted a notice on the front doors of the hotel that "concealed" firearms were banned per MO law. I just wondered if the fella I saw had found a way to carry while staying within the law. The sign did not say that firearms were banned, just the concealed ones. Pretty crafty if that is what he was doing. Don't tell the antis about the "loophole" if my suspicion is right.
