There are one-runway municiple airports all over the country that might have a gate with a padlock, but you can drive around it if you forget your key.tomc wrote:Most airports have two controlled access areas: secured and restricted.
Alaska used to make it mandatory that all pilots carry a gun and ammo in their survival kit, I think they did away with that about 10 years ago because pilots flying from AK to Canada couldnt' obey both laws at once.
