This is slightly OT
If you are ever in the Chicago area stop in at the Museum of Science and Industry. There is a WWII German U boat that was captured off of the coast of Africa. When captured the Germans were trying to scuttle it. We were able to stop it from sinking. The Nazi's were not told of it's capture for quite some time, and the enigma machine on board helped to dramatically change the war.
It is really cool, if you are into history.
