The big treat of the day occurred as I was leaving Wargo. About 50' north of the access road was a pair of Sandhill Cranes; I had never been this close to them. I scurried to open the passenger side window of my car, contort myself over the divider between the seats, and squeeze off some shots. Moral of the story: always carry your camera, mounted with a telephoto lens, and leave it turned on.
