Seeing as how the horses are behind a fence in the video below, it might just be that this inquisitive elk wanted to see how the other half lives. The horses were none too happy with their spectator and decided to make it known. What follows is an awkward confrontation that leaves no clear winners, but makes for an entertaining sight.
The video was filmed and uploaded by Andy Hall. Hat tip to the Boone and Crockett Club.
