This was taken in the Great Smoky Mountains National Park. It was a cold food storage shed for a family that live there long ago. For those of you have seen my image of the "Rock Wall" it starts here bottom right.
I love these old, useful buildings...and this one is even more charming with the aged roof line. Nice setting as well. You might try chopping it to get a closeup of this building...if you have the pixels for it. Looking at your range, I think you do. Maybe you would have fun going really close and trying for contrasting textures?
