Your cars are not safe this time of year at Mammoth Hot Springs in Yellowstone.

Rutting bull elk are prone to take their frustration and raging hormones out on anything that stands in the way of their cows.

Just this fall, over 10 vehicles have been gored by frustrated bull elk.

Extra volunteers are hired on every year just to keep elk and humans as far away from each other as possible

Elk eat the manicured grass and walk among cars, buildings and people.

Idaho Tourist Oneil Schwartz says, "This is just part of Mammoth isnt it? This is what Mammoth is about, especially in the fall."

Sometimes the close interaction comes at a price.

Numerous cars, and trees have fallen victim to frustrated elk this year. None have had their antlers removed so far.

Last year a particularly frustrated bull had his antlers taken off because he took his anger out on too many cars.

Yellowstone security keeps cars moving and officials instruct people on foot to keep a safe distance from the rutting animals.

Oneil admits, "We're all like to get a little closer than we should."

The park closes for the fall on November 4th.
