That Uneasy Feeling

I had to pick up a friend at the airport tonight. The flight was late, so I went up to where the secure area empties out into the rest of the airport. There were the usual TSA critters hanging about. I always get a little uneasy walking about armed in close proximity to borders that if I were step over, would instantly make me a criminal. Does anyone else who carries get that uneasy feeling sometimes that the only thing separating you from getting a close up view of the tile floor is a thin layer of cotton? It’s not illegal to carry outside the sterile area in an airport in Pennsylvania with the proper licenses, but I’m not sure that matters a whole lot to the Philadelphia Police.
