I've watched this happen during almost every visit my family has made to Yellowstone National Park. You'd think the tourists would learn, but no. A new video share shows a bison in Yellowstone explain to a visitor that no, he does not want a selfie, but thanks.
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.
