Is it the weak dollar, the war in Iraq and France's resistance to it, or the events of September 11, 2001 that's causing a significant drop-off of Americans in Europe?

The Chicago Tribune published an Associated Press article written by Kim Housego on the possible causes as to why Europeans are seeing less American tourist.

This is the best quote from the article: "We simply don't like each other anymore," said Jacques Milbert, a mustachioed Parisian taxi driver. "If the Americans want to stay at home and eat burgers, that's their problem, not ours."
