Trips gone wrong: Movie moments

When you're planning a trip, everything works like clockwork. It's only when you hit the road -- or the sea or the air -- that it all goes to hell. Such adventures may make for great drama or great comedy, however, and Hollywood has made the most of them. Take<strong> "National Lampoon's Vacation" </strong>(1983), in which Chevy Chase takes his family to Walley World, only to have car problems, family problems and Walley World problems. <i>Lesson:</i> Don't let your mind wander, especially when you've tied a dog to the bumper.
