"Oh yes. You should always know where your towel is," he explained happily. Ford was always glad to share a few tips with other travelers, and there was nothing more important than knowing where your towel was. "You can wrap it around you for warmth, lie on it on the beach, wet it for use in hand-to-hand combat, use it to sail a very small raft maybe, put it over your head to ward off Ravenous Bugblatter Beasts, all sorts of things. Besides, it really impresses the strags, so there's the psychological value too." It was very often hard to tell if Ford didn't know that he wasn't making much sense, or if he knew and just didn't care.
