I bought this book at a bookstore, and after my journey I am so impressed with it I had to write a review. I am very surprised to see there isn't one yet!
This book has everything: the scenic drives, national parks, camping spots, hiking trails, rock climbing areas, mountain biking trails, state parks and forests, discussion on each major town in the Southern Cali - Nevada and Four Corners area (such as place to camp, local coffee shops, the bars with the jam bands)....all this with a special emphasis on the "budget traveler"....and all presented in an organized fashion.
The maps in the book are invaluable. each major downtown city area is mapped well, as are all the national parks.
The sections also recommened hotels and restaurants, but the emphasis is on local hotels rather than chains, and many times the chains are much cheaper. Promoting the local businesses is certainly commendable, but don't commit yourself to their recommendations there unless you feel you have to make advanced reservations.
I spent 8 weeks on the road and all I had was this book and a map of the country to guide me. This book had everything I needed (and more). Thank you, "Let's Go" writers and editors!
