Where?
Sorry, it was Bimini in the Bahamas in 1985. I got geographically confused. I was on a dive boat at the docks. The captain told us to go below after dark and show no lights and not look out of the portholes. But I peeked. Uniformed government agents who had checked us in during the day guarded a very large operation where they loaded cigarette boats for much of the night. The captain pointed out an unmarked boat with about 20 armed men not wearing uniforms. He said they were cops during the day and pirates at night. Incidentally, a man with a clipboard briefed each boat as they left on where the cutter was and where the radar plan was.
