Open water certified here. Truth be told... haven't been back in since. Dived several springs here in Florida. Certified at
John Pennekamp in Key Largo.
Coolest dive I've done was a night dive at Kings Bay in Crystal river. Cavern dive. We weren't certified but by luck had met instructors that invited us and took us down. Night life comes out. All the divers with flashlights looks cool too.
