I just recently took the course (Nov 3-4). It makes for a long weekend. On Saturday, you are pretty much there from 8 am to 10 pm with hour-long breaks for lunch and dinner. The history about the area is fascinating, although the buoyancy section is questionable. Whether being able to swim through hoops really transitions into a true respect for the environment, i.e. staying off the bottom, out of the plant life, and not antagonizing the fish is a bit of a disconnect to me. (As I witness many individuals who had an easy time navigating the obstacles and yet planted themselves on the ground during the night dive, kicked up silt, and dragged the hydrilla with their fins.) It would seem much of the day's discussion hadn't quite seeped in.
The water itself is beautiful (and a little cold). The turtles are truly wonderful to watch, and the "fountains" are simply amazing. I would encourage people that have an interest in understanding the underwater environment to take the course since it does offer a unique perspective, but also, take heart that it is the only habitat for several unique species. So we must take ample precautions not to destroy their homes and breeding grounds. Overall, it's a weekend well spent and I look forward to going back and helping out.
