I managed to visit Cottonwood School in 2021.
I saw a Facebook post yesterday that the new owner of the farmland where this old school is located burned it down.
I can see his point. The place was in poor condition and it was a liability hazard. There is the issue of people venturing out to see the property, creating a nuisance, and trespassing. There are a lot of old places that are far beyond saving. Get out to see them while you can.
