Two bull elk were sparring in Estes Park, CO when their fight spilled into the middle of the road. Bull elk’s testosterone levels can increase 1000x during the rut, and they become extremely aggressive.

According to the description, the person that was filming this video literally had to duck out of the way because one of the elk’s antlers came crashing through the side mirror and through the open window of the car!

“Driving through the town of Estes park and these two male elk were fighting off to the side. One elk dominates the other and forces him into the street, taking out our side mirror on our car. I had to duck away because an antler swung into my open window and almost caught my face! Everyone including the elk are fine.”
