My OW Instructor was Mark Barringer. We did our cert dives at the same quarry, so I am gaining a lot of familiarity with it. My dive buddy (who is currently going through DM training) is Michael Goodman (a member here at SB). Michael and I are Scout leaders, and he's taken the lead in getting a number of our Scouts certified. We plan to do a liveaboard Bahamas trip in 2012 for our Scouts. (We'd do it in 2011, but we're taking them to Philmont for backpacking.)
Just a quick OT: I'm glad to see there are still Scout troops out there doing adventure training. All the ones close to me are run by mothers who think they have Cubbies. I wish I could get back into it, but with my deployment schedule, it wouldn't be fair to the Scouts. Having a leader disappear for a year at a time doesn't work.
