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 calf had been separated from its mother when the herd crossed the Lamar River. As the calf struggled, the man pushed the calf up from the river and onto the roadway.
