This globalized world seems to give many an international perspective on things, and it's hard not to want to live in a place with cultural diversity and influences. Places like New York, Seattle, LA and SF feel way more international and diverse, and once you're there, you don't imagine yourself going back to, say, a place like Dallas. Nothing intrinsically wrong with it, but different strokes for different folks. I'd personally feel like I had traveled back to the 20th century if I had to move there.
