Pretty much self-explanatory. Bears are not to be trifled with, no matter how winsome they may appear. Between the funny hat and the unicycle sits 800 lbs of destructive power with jaws that can crush a skull, paws that can break a spine with ease, and claws that can turn you inside out with one swipe.
If you encounter a Bear, offer it salmon, or cash, or both, just to be safe. Tell the Bear to wait while you go get more salmon and cash out of your car, then drive away to safety. But make sure the Bear does not get your license number.
Here's a Bear Safety Video for your enjoyment. But remember, your best protection against even the most fearsome Bear is: always go into the woods with someone who runs more slowly than you do. Then you don't have to outrun the Bear. You just have to outrun your friend.
