I'm not a big fan of Chicago (there's something disconcerting about the city that I don't like and can't really place, but I can't explain it), but I'm not a huge fan of New York City, either. The people who live in both cities are fine, but I'm not chomping at the bit to live either place. Chicago has some of the most awesome museums, though.

I like LA and London, though. People in both places are really friendly (God, you should see how some of the people reacted excitedly when they found out I was American in London, mainly because I "didn't really have an accent"), and the scenery is pretty fantastic.
