I've had the opportunity to visit Dachau, and several of the 'feeder' camps around it.
Pretty creepy place.
That doesn't even begin to describe it.

In 1946, I went to Dauchau, Andau, and Auschwitz. A "living history" trip compliments of my father, who was working with the German re-construction effort. "Creepy place" does not even begin to describe it.
