Yellowstone National Park
This Buffalo was alongside the road in the Lamar Valley at the bottom of a steep slope. While trying to capture his image I noticed a dog coming my way from behind. Thinking it strange, I turned to watch. That's when I realized the dog was a coyote making a bee line my way. I could only back down the road as the slope on my other side was so steep with a buffalo at the bottom of it. The coyote made it to the road on the opposite side of me, but just continued on his way down the road. Once it was out of sight, I returned my focus back to this buffalo which was unphased by the event.
