I haven't been to S. America or Antarctica. I will probably hit S. America before Antarctica. Though I will probably see Europe, and Asia again before S. America. But who knows.
I guess it depends on what you like to do. I live here, and I'll admit I haven't really travelled alot within. Having said that, there are plenty of great things to see and do.
It's fluid. We're Americans so we use the 7 continent model. Out of curiosity, do you go by the 6 continent model that combines North and South America or the one that combines Europe and Asia?
I have been to 4. South America and Africa are next on my list, and I think sooner rather than later I will have been to 6. Antarctica ain't ever happening.
I don't doubt it. It's just that I've met so many Americans that have yet to step foot in Europe (other than the UK), South America, or Asia, but they've been to Australia...which is a heck of a lot further.
I have been to several countries in Europe and I live in North America, but have only visited Israel in Asia.
5 of the 7. Still need Antarctica and Australia. As to Asia, I've been to Japan but I'd really like to get to the mainland.
4. Stil need: Antartica (not going to happen) Australia (Like Sandballa said, not exotic enough for the time I have to travel) North America (not to high on my to do list)
