There is a reason

Driving in Central PA, farm country is pretty scenic even in winter. We happened upon a couple of farms where the corn stalks were stacked differently than we had seen before. We stopped to grab a couple of photos.

As we were driving away, the farmer happened to be walking along the road so we stopped to inquire. They are stacked like this to allow them to dry out and be used for bedding.
