My first thought was that the stag was badly injured. He trotted across the rural Wyoming highway wrong, dipping with every third step. Clipped by a car, maybe, I thought, mentally cringing at the internal damage that would have done. I pulled over on the shoulder, but by the time I got out of the car he had vanished.
The land was only moderately hilly, so I could see for a good distance, and the grass was waist-high on me: not nearly tall enough to hide an adult deer. I had taken my eyes off the stag for just a moment and now he was gone. All I could see was a flock of small birds swirling in agitation over the ditch at the side of the road.
