No old barns here...
The barn on the right was built recently and is already filled with burley tobacco. You can see the tobacco leaves hanging down below the side walls. That barn should have very good air flow with all sides open at the bottom.
I'm not sure what the other barn will be, but I am guessing (only guessing!) that it might be a curing barn for dark tobacco. In dark barns, a smoky sawdust and hardwood-slab fire is kept burning on the barn's floor. As the smoke rises through the tobacco leaves, they are flavored and colored.
These barns are located near Fairview, Kentucky. I think they're still in Christian County, but just barely.
