gotta say these travel horror stories are fun to read!
like others in this thread, the only real "anxiety" I feel is very poor sleep the night before if I go to bed knowing I MUST get up at a hard time early the next morning for this very important event (the trip)......
being the son of an airline captain (and of a stewardess before she married my Dad), I've had a ton of travel experience since I was about two months old, so am comfortable with it all......
those things, though, that we can't control and that have the potential to ruin a trip are frustrating......
