We just returned from a three-week cross-country trip, with a four day stop in Yellowstone. This book was o.k. to read before the trip to familiarize yourself with the park, but was useless as a reference guide once we were there. We basically gave up on it and used our Frommers Guide to the Western National Parks. The index is incomplete, the maps are cartoonish and difficult to read, and some of the explanations in the question-answer format with"ranger Norm" made me feel as if they were questioning my intelligence. My husband and I both couldn't believe they showcase this book prominently in the Yellowstone visitor's Centers!
