Here's a little video of us dragging a tire. It's pretty heavy so we've only done this once before, a long time back. He's so willing. You'll notice we don't quite have the one-handed thing down yet, but we're getting there.
(And I wasn't giving John a dirty look, I was trying to figure out if he was filming us.)
Here are a couple cute pictures. Stepping toward the rope and looking at John. I love the way he looks at people. He's so curious and friendly.
