Fun Fact, by Caleb

There is a huge bear that lives in Banff National Park. His name is The Boss and he was hit by a train two times and survived.
Weighing in at somewhere between 650 and 700 pounds. The bear's resumé of dominance is legendary. He is considered to have a home range more than 2,500 square kilometres. He's eaten a black bear. Even though he's been struck by a train, he still uses the railways for travel and foraging.
