I have traveled to:
Mexico
Hong Kong/China
United Kingdom (England, Scotland, Wales)
South Korea
Belgium
Germany
Poland
If I had to live somewhere else other than the US, I would chose England. Of course, since I used to live there, my answer should come as no big surprise. It's as if a piece of my heart is especially drawn to Somerset (a county in southwest England). I don't understand why; but I sometimes feel compelled to return. I must say, it's a strange feeling. I wonder if it's similar to what OTW described....
