In the last couple of days a bear was reported to have attacked a man in his hot tub in Whistler BC. The bear was later shot for being aggressive. Another recent example was a man was dragged from his car by a bear. Apparently the man was a criminal anyway so the bear should have got an award for that.
I find these bear encounters fascinating but I try to keep my distance. If you want a good read there is a book by Stephen Herrero. I believe it is called Bear Encounters. I do not recommend reading it before tenting/camping. However I can't wait to get out there.
