I lost my hard drive so I don't have the article back as yet but according to the author, a PhD "bear biologist", black bear attacks while rare are increasing and most of the attacks happen in remote areas. I suspect this may be so as around people there tends to more easily obtained food sources and a learning curve as it were for bears takes place. Someone encountering a bear in a remote area may run or climb a tree-both of which are more likely to trigger a bear's predatory instincts/an attack than a bear that has been around people and learned something about them. I also read that bears will chase each other up trees and fling the submissive bear outta the tree! So whatever you do, don't hunt bears from a treestand! :D
