Query: Don't go without it

My wife and I traveled the peninsula for two months in a VW Bus with this as our sole reference book. This literally guided us to the best travel adventures ever. Walt didn't miss a thing from road signs, to camping spots, to customs, and to inside local knowledge. Don't miss the "way-off-the-beaten-path" trip to Gardener Cave. Buy it early, and read the whole thing just to get fired up for your trip.
