Hang in there. I promise there is a mushroom in this story. A very wealthy man, named O. C. (Ohio Columbus ) Barber, the founder of the Diamond Match Company, owned a large estate in a little town called Barberton, near where I grew up. There were several huge barns. I remember us driving by just once, and seeing one far off in the distance, maybe Barn #3. My parents told me they grew mushrooms inside the barn. This amazed me as a child. I've never been able to verify it with a picture, but did find this today. "...Established as a partnership in 1920 by Mennonite farming brothers Ira and Menno Yoder — who previously managed the vast greenhouses on O.C. Barber’s farm and purchased them after his death — the business initially raised vegetables, mushrooms, and flowers for Northeastern Ohio sales." Folks used to raise mushrooms in caves and dark buildings. An old picture of a mushroom farm in a quarry in England. Maybe it was greenhouses with mushrooms, but it could have been a barn. Close enough.
