America. No question.
Not sure where I'd want to settle. If the better half was with me I wouldn't move from where I am now. However, if I hit the lottery before I met her here's my thinking:
South has hurricanes, North has snow. Midwest has tornados, Northwest has rain. I guess I'd probably stay in PA, although I'd probably move more toward the center of the state, or perhaps Ohio. The Southwest seems appealing, but with the Mexicans coming over and water shortages I think I'd rather stay away...
