I first noticed the object in the green square on the road, and quickly identified it as belonging to our neighbors. A closer view is shown below.
That's our neighbor's blue tractor pulling a grain wagon, that appears to be laden with corn. It's headed back to the grain bin, so the combine is probably not far away.
Here's a closer view of what's in the yellow box. Sure enough, that's their yellow combine making its way through the field in the valley. A check of their records indicates that field was harvested on October 5 and 6. In the image, the field appears to be less than half harvested, and the shadows seem to mark the time of day slightly before noon, so my neighbor's comment on the previous post that the image was taken at 11:03 AM on October 5th is probably as close as we'll get. With that knowledge, I think we can all sleep soundly now.
