Second the bacon grease, or cook the bacon on the camp stove and pour it about. I've used honey, almond extract, anise extract, anything sweet smelling. Any kind of donuts. Soak terry cloth rags in the almond and anise extracts with cinnamon and hang them on trees. Pour the honey on a stump or log where you want the bear to stop for the shot. We would have PVC tubes onthe side of the tree and fill them with bacon grease. Also a good way to measure the height of the bear. Put it 5 or 5 1/2 foot up the tree, small bear can't reach it.
