Good morning, oddly enough of the only 4 divers Scuba earth shows in PR one is right there in Caguas :) You might try PM’ing him.
20 years ago the USCG offered me a job there but I failed the Spanish test :( That and I found out the locallity pay was ziltch. I would have been paid about half of what the USAF was paying me :( That would have really cut into the diving :(
