So, speaking of log books. I am a bit OCD, but isn't that what you want in an anesthesiologist? I chart all day at work, so I guess it's natural to feel as though I need to chart my dives. I just got back from my first liveaboard - Calipso - Galapagos - Awesome - see my post in South America - and I dutifully logged each and every dive ad nauseam to include sealife Genus and species, etc, etc. I received some good-hearted ribbing about it during the trip, but Guess what? On the last day my log book was borrowed by several people to help reconstruct the trip and their own logbooks!
