For 25 years, the author led National Park Service divers to submerged wrecks. Very exciting and informative.From Florida caves to Southwestern ancient ruins covered by reservoirs and Alaskan WWII submarines.
I am a fan of our National Parks and that is what led me to read this book. It is written in such a way that you feel like you are sitting with a friend and he is sharing his adventures while diving for NPS. It is amazing some of the things the author has experienced, and also sad that he has lost so many friends due to diving accidents. This is a great book. I recommend it.
