The SU must have decided he had enough of looking at all that cement in the foundation of the garage that burned a year ago. He's been busting out the walls with the end loader, and I imagine that the floor will be next. He's hauling it off to use as "fill" in a ditch. I go help him get the log chain on the pieces and hook it up to the tractor so he can pull it. And off he goes, and usually with a couple of "slabs" in the bucket too.
When he gets back we'll have lunch. A nice grilled top sirloin. Yum.
