re: Grizzly bear kills husband, wife and their dog at national park in Alberta, Canada

Re grizzly speed, worked in Yellowstone one summer & several of us were riding down a 2 lane, straight road. Out the blue, this huge grizzly came loping past us & we were cruising at 35 mph, the Park speed limit. We were so shocked we pulled over & stopped. And he was quickly out of sight. There are a ton of beats attack videos on You Tube & in all of them the charging grizzlies are hauling arse. One thing that seems to be common is the bears all seem to go for the human head first.
