Good article.  I have had several run-ins with bears, but always managed to back away or get the bear to do so.  One thing;  menstruating women can attract bears.  My dog team will pick up the scent of women on a trail a half mile away (no, I don't ask them if they are menstruating).  I assume bears can do the same, and this may have been a contributing factor in the recent attacks.  Just sayin'..
