If you visit Yellowstone National Park now, you'll find feeding bears solidly in the "don't" column. But, there was an era many years ago when people were not only allowed to feed bears in Yellowstone, the practice was sort of encouraged.
Many will see this video as a sign that enemies can become friends, but I can't help but wonder what would have happened if a glass door had not been between a dog and a bear.
Based on what I've just watched, I believe this might be the worst year ever of people behaving badly with wildlife. A video has gone viral showing a woman hand-feeding a bear a chocolate chip cookie and I'm beside myself.
