It was so big. A giant peace symbol on the side of the ship. (The bottom leg was missing, so it was more of a Mercedes symbol.)
Now I knew why the U.S.S. Forrestal side cleaners got their liberty cancelled and had to return to the ship in Barcelona. They had scrubbed a mile high peace sign on the seaward hull where nobody would see it. The tide had turned, and the seaward side of the ship was now the shoreward side. Everybody saw it then!
Barcelona is too nice a port to have a short liberty at. I got to buy a guitar there, anyway, and met a very nice prostitute who called me a cab and told the cabbie not to rip me off and even paid the fare, and I never even used her services!
