I'll name a few, first of all, outside of my country.
Australia - One of my first selections for countries to visit.
Canada - I've always wanted to visit my Northern neighbours, and I would like to visit during Winter (yeah, call me crazy, I know

).
Europe - I'd love to visit the UK, Italy, Switzerland, The Netherlands, and a few others.
Japan - Definitely my choice to visit for Asia. Some cool stuff there.
As for the US:
Chicago - I was a huge Cubs fan, and I've always wanted to go to Wrigley Field. There are a few other sites I'd like to see.
New York City - I would've loved to see the WTC (if they were still there). A few of my friends loved visiting this city, and I wouldn't mind going over there someday.
Hawaii - Why not? Hee hee.
To any ski resort - I've always wanted to go to one of the ski resorts.
