This article from CNN does a pretty good job summing up why American’s don’t travel outside America.

I have more to say on the topic, but for now this will do.
If you are too busy (lazy?) to read it, here it is in a nut shell;
1. We have everything we need here, why travel over seas at greater expense and risk for the same thing as here.
2. We don’t have time.
3. We don’t have the money.
I have touched on most of these things in the past, so it will not be news to regular readers of this blog… It’s point one that I intend to rant a bit about when I get time.
