We were turkey hunting in the Allegheny National Forest. My brother told me later that a bear circled him, working closer. The bear came in close and stood there staring at him. He took out a sandwich and threw it at the bear (dumb). The bear ate the sandwich, wrapper and all. It stood staring at him some more. He yelled at it, it did nothing. When he lit a smoke, the bear took off, never to be seen again. In bear season a guy who hunts in the area tagged the bear. He said that it circled him and came in close, staring at him. Where bears are hunted, that kind of behavior gets rewarded in the end with lead, thus eliminating the behavior from the gene pool. A bear that acts that way won't last long. Knowing this firsthand, it's not a stretch to imagine one climbing my tree for a handout.
I wonder if some bowhunters were starting bad habits in the bears by throwing their sandwiches at some.
