Countries I've been to:
Canada
Mexico
Cayman Islands
Jamaica
Bahamas
Switzerland (brief layover, would like to see more of it!)
Israel
England
Of those countries, if I absolutely had to leave the US, I'd move to England. I loved it! Plus winters wouldn't be too horrendous, no language issues, and there are enough things I really like and can get there and not here that it would be an even tradeoff. Oh yeah, and there's national health care.
