We tried using this book on a recent trip on Route 66. Not only does he use outdated maps, with old street names, but has he even tried following this book himself? Most of the time, when we tried to follow his directions, we got completely off-course. One memorable time, he got us on an old, run-down alignment that literally had only one lane! Luckily, we had only one on-coming car to pass (which was accomplished by both cars driving on their respective shoulders!) I think he just phones in the "updates!" The only reason he gets even one star is because there is some interesting history in this book. However, I wonder if any of his historical facts are correct, since he gives so much misinformation otherwise!
