The information about the German sub is interesting. I didn't
know it still existed.
  When I was a little tyke during WWII, we lived in Philadelphia.
One day my parents were excited because we were going to see
something special. We went to the dock, for admission bought a War
Bond, and went through that German submarine. I remember it, but
it wasn't until years later when the story about it's capture was
published, that I realized it was the only one captured and
therefore was the one I saw.
