Does your husband grain farm? If we are successful at taking down all three, the third will be turned into a sauna and changing room. I miss the sauna from my childhood. They would also make a good rodent free place for food storage. Now you got me thinking... I wonder if you could insulate it and do the whole freezing 5 gallon buckets of water through the winter thing, and set them in there once frozen, making it a year round off-the-grid cold storage....
