forget the scent, use a predator call. I've called in blackies using a predator call. One of the first things they tell you not to do on Kodiak Island is use a predator call because the bears will come running expecting an easy meal. There is actually a pretty good DVD called "Call'n Bears" that might be helpful to you. If you know 100% that the area you are going to holds bears then calling is probably your best bet.
