We were lucky enough in around 1980 to be in Key West at a little fort they set up for the Atocha treasures. It was very well guarded but set up so you could pick up the gold and silver bars. When we were leaving, we saw a guy get out of a car carrying a small box that looked very heavy and had thick gold chains draped around his neck. We decided later it must have been Mel Fisher. That was a fun trip. The jewels in there were fabulous!
