Since my last post in 2005, I've added several countries:
Argentina
Brazil
Uruguay
Paraguay
Puerto Rico (depends, if you count this as a country instead of US commonwealth)
I count Puerto Rico as a US protectorate. Which isn't to say it is not it's own country. It depends on your definition of the word "country" though, I would imagine.
Foreign Nation-States that I have visited:
United Kingom
United Netherlands
Federal Republic of Germany (Nordhein-Westfallen)
Italy (twice)
Greece
France (three times)
Monaco
Switzerland
Belgium
Scotland
England
Canada
Mexico
Lots of states--I think there are only about 5 or 6 I've never been to (Pacific NW and the desert).
This is the first summer in a long time that nobody in our house is going to Europe. Mr. NUB&B and I are going to Bermuda in June and England next May, daughters and I are going to Paris in March for spring break.
