Been to:

1) N. America
2) S. America
3) Europe
4) Asia

to go:

5) Australia/Oceania
6) Africa
7) Antarctica

In my ever changing list of places to go, I have New Zealand and Egypt topping the list so that would take care of #’s 5 and 6 ( Although admittedly, Egypt woulnd’t really feel like Africa). Antartica is going to be such a problem to get to if for no other reason than the sheer cost of getting their.
