We were near the end of the trail from Penetanguishene to Midland; I was idly still hanging onto the camera, not expecting much. The light was fairly poor. There was a rustle and a chipmunk made a break for it in front of me. He looked like he had been about to cross the path, but we got in his way. He ran around the tree, then dived into a gap near the roots, scooted up the hollow and hung inside, poised to see what we would do. A gap in the canopy meant I had enough light. I hauled out the camera of course.
