I was reading an article a while back, and they had pictures of the damage that hogs do to agricultural fields. It also showed woods where the hogs would rub trees, and basically turn the ground to mud. It did not explain what they were after in the woods to congregate like they did. It was shocking, the pictures they had of the aftermath whenhogs wentthrough a field. They basically flattened half of this grain field in the picture.

No wonder the State of Wisconsin put up an alarm flag when some were spotted in Wisconsin.
