Finally, if you travel Europe and you see two German groups at a campground, you might easily be able to distinguish them. Eastern Germans usually sleep in tents, while western Germans prefer to travel with trailers. We did not find a scientific explanation, but one might posit that it's rooted in western Germans' longer experience traveling the world. Furthermore, many young eastern Germans couldn't even afford a car under communism. Trying to buy a trailer would have been more expensive and nearly impossible for most eastern Germans. While those in the west were able to explore beyond their borders, eastern Germans remained practically imprisoned by their government for nearly 30 years -- until 25 years ago.
