Be safe. I've been where you're going and it's not too bad. Just remember that the zillions of shoe clerks truly believe that their enforcing of asinine regulations truly makes the USAF a better war-fighting machine. Everyone really believes that they are the "tip of the spear" these days. I don't know how many times you've been, but once you get past being treated like a 10 year old it gets a lot better.
