OK, two cents~ Shadow Divers is an excellent book, I've really enjoyed reading it, but it didn't teach me s____. (I also enjoy Grisham, King, some others) I think there is a possible (or published) rivalry with the people being discussed (something like some dive shops I frequent). That said, when I would like to understand the methods and practices of diving I have several books authored by Gary Gentile, very well written, comprehensive, descriptive books that help direct where I would like to go. Reading SD illustrated how these methods/practices were used to Identify an awesome wreck (the holy grail), and honestly, how it affected two men. Obviously, there were other people involved in the work (teamwork) required to get the job done. I have not read Mr. Gentiles book, I intend to because I get the impression that there is a community of excellent divers on the east coast and I'm interested in all the opinions and actions, not just Gary's, or JC or Richie K. I believe from reading Gary's books that he is a stickler for accuracy and that he likes the idea that all aspects are examined. What a concept. I'll thank JC and RK for inspiration, I'll thank GG for education (and inspiration). Motivation and method seem to be two pretty important attributes to accomplish what you set out to do. I haven't met any of these people, I can get what I need from Gary by reading his books and further discussion with other divers I respect, as for RK or JC I'm really not willing to spend $175 to have a dive and question and answer session with them. I don't have any animosity towards any of them, I don't know them to form an opinion or impression, but I think it's important to point out that Gary has given back to the dive community through education, at a better, more practical price. Maybe I'm wrong, set me straight, where can I find a book on diving education from JC or RK?
