Thats the problem they don't seem wild but they are and unpredictable . They lose the fear of people and thats not good, both for them and people.
We have a lot of grizlys here and if you don't know the difference it can be deadly. The only thing dumb enough to challange them are wolverines and the bears back down. We have a couple wolverines in the woods on my way to work. Have seen them once (in my car) too close for me.
