I agree there’s just no excuse when flying. It’s pretty startling to hear how many firearms are confiscated during check-in. Thousands per year.
A number of years ago we were doing a project at MSP and we had to drive in to the flightline area. Our vehicles got a once over every time we entered, but usually not searched thoroughly. The one time my partner’s truck got searched he had left a couple 12ga shells in his console after a weekend of trap shooting. They were not impressed. Stopped short of a cavity search, but he learned his lesson!
