content: This book is very helpful to the novice or experienced off roader. It is very descriptive of trails, landmarks, and gives you a accurate mileage counter at needed intervals along the way. This book grades the trails into three classes, easy, for most high profile 2wd or 4wd vehicles, moderate, for 4wd vehicles with lower gearing and somewhat experienced drivers, and then there is difficult, for the experienced driver with specialized modifications like diff. lockers, suspension lift, recovery devices and the willingness to have some damage done to the body or drive train of your vehicle. I would highly recommend this book.
