i have seen a documentary on the polar bears of hudson's bay and churchill, manitoba..... compared to other bear species, polar bears are more likely to consider humans as prey... and those bad boys are twice the size of a black bear!!!!
black bears are not typically more than a nuisance, but this is early in the season and there will be cubs, which makes for more dangerous encounters......
at any rate, the little shake up was a cheap enough reminder that lapses in vigilance just like that can lead to real big problems in a heartbeat..... lesson learned!!
