When I was researching my book, Great Montana Bear Stories, I camped out at just about every location that someone had been killed at night by a bear. Trout Lake. Granite Park. St. Mary Campground. Many Glacier Campground. Elizabeth Lake. All these cases (which are spread out over 50 years) involved bears that had made a habit of eating trash or raiding camps. That's why it's imperative to keep a clean camp. I've also tried to drive "Food conditioned" bears out of camps and had them eat every scrap of food I had, in spite of shooting over their heads, barking dogs and (once) hurling a pulaski at it. The tragedy is, it's rarely the slob who pays the price for feeding the bear. It's the next poor guy to come along. In spite of all this, I can still sleep in grizzly country at night, but am prepared for trouble if it comes. Electric fencing seems the best deal if you don't mind the cost and weight.
