A high-school colleague I knew spent a year on a student exchange program in Montana. This was way back in 1976. He learned a lot, made some good friends and had an all round good time. His one eye-opening moment occurred in a Geography lesson at the school - having spent a lot of time learning about Montana and it's surrounding states, he asked the teacher when the syllabus would move on to other parts of the world. The reply was, "It is the duty of the rest of the world to learn about the USA, not the other way round". That was when he knew there was a problem!
