To be honest - I have my doubts on the bear spray. I've seen studies, I own it and carry it. I've done some basic training with it. If conditions (wind, humidity, distance) are perfect I think it will work. My life never has perfect conditions.

So I'm working hard on avoidance! Clean camp, camping away from animal trails, "singing", being aware of surroundings and if you have other suggestions for avoidance, great!
