It becomes a problem when the Black Bears finally realize that screams don ' t mean a damn thing . We had a bear in my neighborhod a few years ago , he had to be closing on 500 lbs . Nothing , and I mean nothing , would get this bear to go away . One night he was trying to get into the shed where the garbage is . Doors are half inch plywood and 2 x 4 construction . I see him outside so I go out and try to scare him off . He ' s not having it . He looked at me , grunted , and went back to attacking the shed door . My dad came out and through a baseball at him , pinged right off the back of his head . Again , grunt , back to the shed . He ended up ripping one of the doors clean off . Been awhile since I ' ve seen him , pretty sure he was killed during bear season .
