There is a book, I think called When Bears Attack or Bear's Attack. Not really sure of the name. It has two volumes now and it is a series of first person naratives (if they survived) or rescue team narratives of people getting attacked by bears in Alaska. Good reading on the plane, and you will learn what not to do.

Do not go near bears period but especially if it is a mom and baby or a bear that is eating or stashing its kill. Most people were hunting in thick brush and came right on top of either eating bear or mom and cub. Or they shot an animal, bear is watching, and bear wants animal. I think bear wins.

Now if you see them, their behavior reminds me of dogs. I have watched them for many hours clamming on a beach. One time while in an outhouse, one walked about 10 feet away on the way to the beach. Did not even notice me.
