There's an old saying I've heard many times from friends and family in Wyoming that pertains to wild bear sightings that goes: "you don't have to run faster than the bear to get away, you just have to run faster than the guy next to you".
Imagine what you would do in this situation. You're a deer (I realize that's a reach) and you're being chased by a coyote. What do you do? If you're in Yellowstone National Park, you hide in a nearby bison herd which is exactly what just happened as a new video shows.
When you visit national parks in Wyoming, you never know what might cross the road in front of you. For one driver today, that was a wolf pack that was crossing the road in Grand Teton National Park as their video share shows.
