Our family recently drove Route 66 eastward from Santa Monica, California to Gallup, New Mexico. I used this book during the planning stages to identify fun things to see and do. I really loved the descriptions of possible side-trips, such as London Bridge in Lake Havasu City, the Petrified National Forest, Walnut Canyon National Monument, and many others. This book does not contain maps, however, or instructions on how to stay on Route 66; the actual road signs are not clear at times, and instructions (or a good map) is essential. While I found this book full of useful information about sights, I used it as a supplement to the EZ66 Guide (which had great maps but not much info on side-trips). Both books together worked great, although I chose to take only the EZ66 Guide with me on the trip.
