In the spring of 1968 (age 19) I carried my cased Remington 870 onto a flight to Washington National (now Reagan International) Airport. The stew put it in the coat closet next to the forward boarding door. She handed it back as I deplaned & said thank you for flying Delta.
In the summer of 1972 (age 23) I carried two souvenir rifles from Vietnam in a miniature golf bag through the San Fran International concourse, with the bayonets sticking out. The customs guy said welcome home.
In the summer of 1982 (age 33) I carried six handguns from Germany in my suitcase through Atlanta customs. They checked my Form 6/Part II & said have a nice day.
As to the subject of this thread, I say let passengers bring on board their well behaved potbellied pigs! At least one airline should announce a pig-friendly pet policy. Let the muzzies stay away in droves & threaten reprisals! In fact I wish they would all just go away.
