Drop the Rifle and Pick up the Bear Spray

Brigham Young University bear biologist Thomas Smith says that guns aren't necessarily your best option when facing down one of the beasts. Smith and his team analyzed 20 years worth of incidents in Alaska, and found that the wilderness equivalent of pepper spray effectively deterred bears 92 percent of the time, whereas guns only did the trick one-third less often. (He studied polar bears, too, hence the picture, at left, of an unconscious mother and her cubs. And yes, he did get away before everyone woke up.)
