I don't feed them any more, they come for the apples from the trees I have or the blueberries, blackberries or rasberries that are in the swamp by my house. When the blueberries are ripe I see a lot more bears until the berries are gone. I used to put out lots of day old bread and what ever else I could get, just to see the bears but like you said they get to friendly. I had one bear as soon as we got to the house on the weekend he would be out on the lawn waiting for food. I thought it was just a coincidence, but he was there every friday for weeks he would eat everything then leave.
