Yellowstone National Park officials have put out a news release to remind tourists not to approach, engage with, or otherwise irritate Bull Elk during mating season, which has started this month.
I don't normally wish bad things on people, but in this case I believe the human deserved it. Someone in a car in Estes Park, Colorado thought it would be a good idea to taunt a bull elk with his ladies nearby. That didn't end well for the car.
I've never seen a bulk elk do this before, but apparently it is quite common when they are "in the rut", and it is definitely rutting season right now.
