Dough - A friend and I hiked through Glacier National Park one year in grizzly bear country. After a few hours of hiking you DO run out of conversation - but you realize you MUST keep talking for your own safety. We would take turns just blurting words out loud. We never encountered a grizzly. When we returned to the lodge though, we learned a man was mauled to death by a grizzly later in the day on the same trail. He turned a blind corner on the trail and suddenly encountered the bear.
