Bieber Mill near Delaware, OH
When I was visiting a friend in Columbus in 1997, he gave me a tip on where to find this mill ruins. It is along the Olentangy River, south of Delaware. It is easy to find, right along Chapman Road. The best view is from the other side of the river on busy Rt 315. From there the side opposite this looks quite large and impressive. This is not typical of abandonment in the midwest and looks more like you are in Europe.
This was just down the road from us. It's a fun place.
