Rimlit Little Doggie (Tetons Coyote)

We were heading for the Sawmill Ponds in the early afternoon to check on the moose activity reported there (and after we had spent the morning there "moosing around"). I had just pulled the truck off the road into the parking area (such as it is) when this little doggie crosses the road, comes through the parking area, and heads down the trail towards the ponds. I just had time to grab the camera with the 100-300 and head down the trail after him. He stopped to turn his head and assure himself that I wasn't a threat and I took this image; then he proceeded on down the trail. I only got four or five images where his eyes are visible, and he was headed into rather harsh afternoon sunlight. Still, however, the experience was the main thing, and the rimlighting is a little different.
