Luis Munoz Marin was pals with my father. And I'm NOT kidding. He had him over to the Fortaleza and his country estate on NUMEROUS occasions. One reason is that I think my father amused him with his colorful stories about his many adventures. Also my father, who has an AMAZING talent for languages, actually spoke Spanish with a Castilian (not American accent). That impressed quite a few folks in PR since it is the equivalent of a high class English accent here made even more amazing by the fact that it was spoken by a Gringo. My father also speaks flawless Russian without accent so when a Soviet ship once came into port, he took the crew all over the island. I do remember my father giving an ultra-large size bra as a gift to a corpulent female member of that crew.
Was you dad with a certain "company" headquartered in Langley, VA?
