Be observant of bear signs as well. A quick search on the internet will show what bear tracks look like. A notice at one park in Canada where black bears and grizzlies coexist made an interesting point as grizzlies (which are not in North Carolina) are more aggressive. Pepper spray and bells are encouraged when in the area to ward off bears. It also tells of the difference between the two bears and what to watch out for. For instance, black bears eat mostly berries and small animals, whereas grizzlies will eat anything. If you happen to find bear droppings, you can determine which type of bear is in the area. If the droppings contain berries and squirrel fur, it is likely a black bear. However grizzly droppings have a strong scent of pepper and contain bells. Just be glad we do not have grizzlies around here.
