Black bear, grizzly or whatever, when a bear is sighted it is wise to head in the other direction—and fast.
The grizzly bear is a wild animal, and no amount of research will change that fact. Whether or not the Park Service has ever been negligent in warning people of the dangers, I cannot say. However, several times I have seen people feeding wild animals within 20 feet of a sign warning them not to do so. When easy meals are presented in the form of handouts the bear will overcome his fear of man long enough to become a nuisance or, unfortunately, a menace.
I question Dr. Craighead's statement that "grizzlies were unaffected by weather." All wild animals are affected by weather changes.
I have often wondered why an old guide I knew never zipped his sleeping bag. Now I know. Looking at it from a bear's point of view, there is not too much difference between a pack of food—a regular source of supply—and a sleeping bag filled with meat. Accidents are to be regretted, but let's hope that the outcome is sound, not based on hysterics. Should we close the old swimming hole because of a drowning?
