The bear hibernation season ends around March to April (the beginning of spring), so it's no surprise that there are more and more grizzly sightings lately at Yellowstone National Park.
Local rangers do a great job of educating the public, enforcing the rules, and keeping Fort Collins' parks and natural areas as safe as possible, for both humans and animals alike.
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.
