Most Rock City Barns you can't see are lost to the ages. This one is lost to a bunch of trees, a house and other possesions of the landowners.
I had driven through here several years ago and didn't even see it - and I was specifically looking for Rock City Barns! However, on my second trip southbound on US11 from Knoxville to Chattanooga right before winter, I spotted it, or at least a small part of it.
I don't have the nerve to pull into someone's driveway and knock on their door to ask for permission to photograph their barn. So, I spent a while driving around the area to see if I could get a decent view. When I deemed that fruitless, I got on the main road and just looked for the best I could get, which is this view - far away with a full zoom.
It's on US11 in McMinn County between Riceville and Calhoun.
