Fortunately, I had the privelege of getting on location during some of the production of Twister--right in my town even!!! I can put all you Axial-Flow lovers at ease. Those were not real combines as some of you may already know. Fairly realistic props, though, as they lured me off the hwy for a closer look. I thought they were exp. machines, because some stuff looked funny. Security also stopped me, adding to my theory, but was told the movie crew had come to town while I had been on a harvest run.
