Ever walk through downtown Edmonton or calgary? If you have, you survived a far more dangerous group of animals.
You have about a five billion percent higher chance of being maimed or killed on the highway driving to/from the mountain, than from a bear on the mountain.
Earplugs. That way the mice won’t keep you awake worrying about bears. Believe me, if a bear decides to visit, ear plugs won’t stop you from noticing
Basically, go out there with the attitude that you are the best killer on the mountain and yogi better f’n run.
