I have been on the Bowfin,(24 hours) off the coast of Florida about 1965, left on a rubber raft for Army Intel training. Paddled ashore and watched the lights of south Fl going south, had to be rescued by the Coast Guard, big surprise to the coasties when they came upon us with lotsa machine guns and etc. The Chief in charge of the CG boat said “shut up” there is nothing there. Got to a pier and found out where the coasties hung out and bought lotsa drinks.
