Tourists' Dangerous Selfies with Bison in Yellowstone National Park

Tourists in Yellowstone National Park are putting themselves in danger by getting too close to unpredictable wildlife, such as bison, for the sake of a selfie. The National Park Service warns visitors to keep a safe distance from animals, but some tourists ignore these guidelines. Bison are the largest land mammals in North America and can weigh up to 2,000 pounds with a potential speed of 35 miles an hour. Visitors who invade an animal's space for a photo almost deserve the foreseeable consequences. It's important to remember that wild animals in national parks are just that: wild. Carry bear spray and keep your distance.
