You all have me thinking with this topic. I live a stones throw from Camp Butler and as most of you know, a portion of that camp was a POW camp for about three years. There were about 850 Confederate deaths there in that time. The portion of the camp that was converted to a prison is now a farm field that is west of the parade ground that is now a private cemetary. Would be a good place for some ghost busters to visit and see if they pick up anything.
