There are several possible key threats here when hiking: bears, cougars, and coyotes. Wolves too if you're in the backcountry. They could be hiding anywhere along the trail, so it's important to have deterrents like pepper spray, bear bangers, etc. So right from the beginning, you have to be thinking about potential dangers and how to deal with them.

And wolves will wait for you at Grandma's house, or so I hear. By the time you make it to the trail, you're all pumped up and ready for a fight. But it's also very relaxing
