We aren't the only ones that need exercise. This is Diego on the treadmill. He got to go first, then it will be Fatty Maddy's turn. What an ingenious way to give your dog some exercise. Except for the photo of the pompous grass in the wind I don' think I have photographed movement. I noticed things in the background are sharp in contrast to his moving legs. It seems so obvious but now I wonder if I could have gotten a sharper image somehow.
