Kimble likes using my treadmill about as often as I do, but he has different things in mind. It makes a perfect train track, and unfortunately, it also makes a great jungle gym. He is fearless! One minute, he was playing down on the ground, and the next minute, I look back and he is on top of it. After a stern talking to, about naughtiness and danger, he didn't climb the treadmill again. At least, he didn't climb it anymore today.
