Just reading this book made me want to join Mr. Clifford's team. The most endearing aspect of the story (and he really does tell it as a story, not just a report of the excavation) is that he's not a Dr. of Archaeology, or History, or anything like that. He just followed (and is following, if I'm not mistaken) what he loves. But that doesn't make him a treasure seeker, at least not in the traditional sense, because he's more concerned w/ the significance of what he finds than it's monetary value.
If you're obsessed with (or even interested in) nautical history, like I am, then this is a must read.
