Storm Over Corn

I was busily gazing off to my left as we zipped along the highway when my wife asked - "would that make a nice picture?"

I looked where she was pointing and was astounded by what was there. The car did a "photo U-turn" on its own and I raced to set up the tripod. I exposed 2 sheets before we were hit by a huge gust of wind, followed by a downpour.
