Midway (aka Sedalia), Ohio- Dorn Schoolhouse
I have to thank Mike Dorn for this one. This is the Dorn School, built in 1890. It's located on Dorn Road, just east of Midway/Sedalia. This is being restored to its former glory! I hate it when the sun is behind the subject I'm photographing, but in this case I wanted to get a photo of the water pump in the foreground. See the next picture in this photoset for what I think has much better lighting, but is less interesting because it's missing the water pump.
Here's a link to Mike's photo of this school. He adds some more personal history/provenance:
