I think, as you said, America is a big place:
A trip from Madrid, Spain to Warsaw, Poland is about the same as a drive from El Paso, Texas to Detroit ,Michigan, or Seattle, Washington to Omaha, Nebraska
2,868 km : 1782 miles.
And that's only half way across the country. A round trip from Seattle to Miamii, Florida is the same as driving from Glasgow, the northen UK to Chennai, India!
So, with so much to see and do inside the US, a lot of traveling internally would be in order before venturing outside the country. Also, we are separated by two oceans from Europe and Asia, so any close international travel would be to our favorite neighbor in the north, Canada, and south to Mexico/South America.
From my "small town background", a lot of people here are pretty focused on everyday life, and they are US-centric. Why spend all that $$$, spend hours in a plane to mingle with foreigners who speak with funny accents, when the truck needs a new set of tires, or we could take the kids to Disneyland, or there's a fishing trip planned? I guess a lot of people just don't see the appeal in going far off places to see things.
Obviously, this does not include everyone.
I'm just relaying fom some of my experience as a country boy.
You know, I bet a majority of Europeans don't travel far either (non-business). There were only three international guests at last October's Subsim meet, and only two from Europe. That tells me that Europeans don't travel any more than Americans. There were three US members at the Amsterdam meet a couple years ago
.
And taking a trip from London to Italy does not count the same as flying from San Diego to Italy.
That's the US equivalent of driving from East Texas to West Texas.
My family has done a small amount of European travel; I've been to London twice, Paris, three times, Moscow four, and then a nice driving trip from London through Ghent to Amsterdam, with a quick jaunt to Wilhemshaven. I'm planning a trip to Copenhagen this Sept
