That's interesting, you've repeated this in a few comments. I am not american, but living in the US, and it's always been my observation that while true, americans seldom travel outside their own country, they do travel, a lot, within their own continent-sized nation. In fact, almost everyone I know here is quite frequently taking little trips, both business and pleasure, be it to see relatives (families are very dispersed) or friends, or just sight seeing. In my experience just about everyone has been to New York or San Francisco, or the Bahamas, Hawaii, not to mention LA, FL, the Grand Canyon, Yosemite, Chicago, New Orleans, etc. At one point or another, just about everyone takes the proverbial road trip across most of the US. And I'm pretty sure that any one point in time, there are more airplanes, packed, flying over the US than on any other part of the world, probably combined. Of course, it may be my own distorted vision of reality.
