When I lived in CO, I lived about three blocks from downtown and in the summer and fall, bear were nightly visitors in my yard. We could not leave bird seed, barbeques or garbage cans out. If we did and the bears came and you called Wildlife officer, you got a big fine, your fault. Still they came as they had discovered an easy life down in the city and they were reluctant to give that easy life up. One fall, a block from an elementary school, a she-bear decided to hibernate under a woman's porch so she would be near easy pickings when spring came. They did much damage in town.
