I forget to post this earlier. These photos are from a drive we took while not mingling with people during the Omicron variant outbreak.
And as we rounded the building he found the answer to my query!
I am uncertain who still burns coal in their homes or barns in Clermont county, but someone must!

If you are a Clermont County or Brown County resident who knows the answer to my question, please post in the comments section! Educate a city girl!
