reading this article I have a wonder as to why these kids weren't accompanied by and adult. Now I know when I was 17 I went out on a 2 week camping trip, but I was in one location, in a friends woods at that. Also I think they had to do something to provoke this bear, note it was a mother and her cub. I think I would have backed away slowly or the old play dead. I don't even know all to avoid a bear attack. There is also the sure fire way of avoidance, do not go where bears are.
