of my time in 'Nam was going snorkeling in Cam Ranh Bay. The water was as clear or clearer than our air and the number of different kinds of fishes, corals etc was simply out of this world. I just wish I'd taken pictures of some of what I seen in that bay. We'd be going along really into what we were seeing and then think to look up and be a half mile out to sea in a half mile deep water that you could still see the bottom as clear as it was up closer to the beach
