Seems to work about 2/3 of the time. For the other 2/3 you may need more persuasion.
Safety belts are not only for fender-benders.
A .380 is a lot better than a sharp stick. Probably enough against nearly all black bears. Probably will work most of the time, even against most brown bears. Sometimes, though, more is needed.
Dang - I used to be good at math! 2/3 + 2/3 = 1 and 1/3...
