It was a Prisoner of war camp and I remember seeing the prisoners in the camp. As I now think about it it might have been closer to Algona, Iowa, but on the main highway Rt. 18. Was only a child then.

Any further impressions from those in the know, as our friend GS would say?
I've heard it said that these prisoners were often admired for their fitness and rugged good looks, especially by the opposite sex. Rumors I'm sure.
