There are apparently two kinds of tobacco cured two differnt ways...Kentucky burley,
is cured in the tall, often black creosoted barns, seen throughout the Bluegrass, and
they have tall slim doors, like shutters almost, that can be opened and closed along
the two sides of the barn. I don't remember, haven't paid attention to any cover,
shelter, or "porch". but the barns I am describing usually are large, have a wagon door on each end, and tobacco is lifted up on the sticks right off the wagon inside the barn.
I suspect the barn modeled here is a much smaller one that would not allow that.
