The U.S.S. Constellation in Baltimore Harbor. Built in 1854, she was a slaveship interdiction ship in the Mediterranean Ocean during the Civil War. I toured her, and I am very thankful I wasn't a member of her crew. The all were either under five foot 8, or had very sore backs. I've also seen her modern successor, the aircraft carrier Constellation. We were in Pearl Harbor when she came in on her way to be retired in favor of the latest supercarrier, the U.S.S. Ronald Reagan.
