I was in Baltimore for business this week and had some free time one afternoon. If you are ever in the area I recommend stopping by the Inner Harbor and checking out the Historic Ships of Baltimore Museum. They have four different ships you can tour for 18 dollars. The US Sloop-of-War Constellation, the US Submarine Torsk, the US Coast Guard Cutter Taney, and the Lightship Chesapeake. The Torsk was on display but the interior was closed due to electrical issues. Being an old Army vet I haven't had much exposure to ships and found the tours to be extremely interesting.
