A quick one. Growing up in Wisconsin, I spent some time in the summers working on a farm baling hay. Hard work. A piece of farm equipment picked up the hay, made it into a square, tied it up with twine and then you had to stack it on the wagon. Once back at the farm you had to pull off the bale of hay and stack it in the barn. In Illinois, I see much more of this form of "baling". I'm not sure why. I also see much more of these "bales" left in the field into winter. Once again, I'm not sure why.
