Hooftober Hayride

How is this for 6400 ISO? I shot this from a moving hay wagon. The figures in the foreground are somewhat blurred due to the movement of the wagon at a slow shutter speed. But the barn and arena in the background are sharp and clear. A nice atmospheric shot summing up what it was like to be at Hooftober. <i>Sony NEX 5N, Rokkor 16mm f/2.8.
