The market is overcrowded with books about Yosemite. There are few outstanding guides and then there is everything else to put it politely. So, why another guide?
Very simply the answer is this little book fills a neat little niche not addressed fully by the others: travel by automobile. Many people, if not most, experience Yosemite by car, driving through the park and jumping out at an interpretive sign to snap a few photos and then jump back in the car and motor to the next stop.
This well written little book identifies and explains what a tourist will see in terms of geology, flora, and fauna at the major stops and near the road written by someone who knows the park. It provides nice descriptions without getting too technical. While one can argue about whether this is the best way to "experience" Yosemite, it does offer useful information and can enhance the experience for those who choose to do so.
The book is well illustrated with color photos, illustrations and maps. It is well-sized for its intended purpose. It offers an alternative for those folks not hiking the trails into the back country at a very affordable price.
