Pre-clearance at Hamilton airport (no band playing as you leave more's the pity) meant we hardly had to queue when we landed in the USA. That felt right somehow.
I'm not sure I'd ever up sticks and move, but I could imagine myself living in America. For one thing the Americans I've met over here seem much nicer than some of the ones I've met in the UK. I think it's a ploy - they export the obnoxious ones to put us off wanting to go!
