Turtles

As I walked across the bridge this morning, I noticed what I thought was a dark brown duck in the river below. But when I stopped to look I saw the duck was underwater, and then I realized it was a turtle, and that there was another turtle in front of it. I stood there as long as I could, watching one turtle, then the other take the lead. When they were above water the sunlight shone on their shells. I could see the white bottoms of their feet as they paddled upstream.
