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.
There is always an uneasy peace between bears and wolves in Yellowstone National Park. That was witnessed by guests (and workers) in the park a few days ago as a grizzly and two wolves came face-to-snout in a showdown in Hayden Valley.
How do you deal with the heat? Hopefully air conditioning is an option for you. For a grizzly in Yellowstone, there's one option readily available in many parts of the park. Head to the river and play hard.
