   When you drive by them you can see that their irrigation systems are big sprinklers on wheels.

   They are attached to a central point and rotate around the field, making a big circle.

   Nice. Joel’s reppin’ the Ogallala. Unfortunately, this massive aquifer is being rapidly drained by the corn/beef industry in the area.

   Bad news.
