Yesterday, my "Missouri River Sunrise" photo appealed to some of my Facebook friends in a way that I hadn't expected. So once again I'm posting something that may seem prosaic to some but which is perhaps meaningful to others.

This one wouldn't exist if my friend Jack hadn't said, "You need to take a photo of those clouds" as we drove east across the state. I resisted -- in part because I was driving and in part because I don't like taking photos from the car. But here are the clouds. And here, also, are the rolling plains of central South Dakota, touched with a hint of green and the promise of another summer. (Jack steered the truck as I took two quick photos in very sparse traffic.)
