After moving across the highway, it destroyed three outbuildings, three grain bins, a large machine shed, and a two car detached garage and broke off numerous large trees at a farmstead. It continued to move north-northeast and destroyed three wind mills and three center pivot irrigation systems and threw 1/2 ton hay bales one quarter mile into a corn field. | |||||||||||
