Rainbow over Franklin County

I was out doing some field work in Franklin County, IN today, between Metamora and Batesville. Naturally, I had my eye on the weather. A squall hit right before I got to my car. As I drove out of it, I looked back and saw one of the brightest rainbows I had seen in a while. It was uninterrupted from end to end, but it was so big that I could not get a picture of the entire thing. It faded after a couple minutes.
