Personally I don't think you have anything to worry about. I've been involved with bear hunting for 30+ years, been hunting them for 20 years and not once have I had a bear get too hostile with me. There a curious animal, there vision is terrible. There nose makes up for it though. In most cases there just as afraid of you (if not more) then you are afraid of them. If it bothers you that bad pick up some pepper spray, that works well for these black bear.
