I was certified when I lived in St. Thomas by Chris Sawyer at Anchorage. Our night dive was the creepiest (surrounded by schools of huge tarpon at Coki Beach). Dove on a airplane wreck. Never went deep enough to decompress. The instructors couldn’t believe I never dove before because I was already an experienced freediver.
I’d like to dive Belize or the Caymans someday. The coolest place I ever dove was freediving on the 100 ft sheer wall at Scott’s Head in Dominica, W.I.
