Stacking the hay wagons has been a fall activity for a few years around here. Our tobacco barns have stripping rooms that are as long as the barn with a loft overhead, this makes a low long room.
These are just right for one on top of another and backed into the room. 


I sure do love your old barn, I try to keep mine up in good condition, but they are not a clean and organized as your's on the inside.

Nice
