My parents have 2 garbage bins that are sunk into the ground with heavy steel lids... supposedly raccoon proof... but at least twice a week they would wake up to find garbage strewn all over the place. They figured it was the raccoons... one holding up the lid, another scrounging for food. Well, one morning they caught the thief... ONE raccoon, with one hind paw on the step-pedal, and two front paws digging through the garbage, and two little beady eyes staring up at my father as if to say "WTF are YOU doing interrupting my meal???" From then on the trash went out in the morning... like, say, when the garbage truck was pulling up.
Another story: This happened to my husband's grandparents. A raccoon took up residence in their attic and had some baby raccoons (cubs?). My husband's grandparents discovered that there were raccoons in their attic, and boarded up the attic fan and any other access they could find. Well, it turns out that Mama Raccoon had been out looking for food and had left the cubs behind. She actually tore a hole in their roof to get to her babies!! This time, they let her and her cubs leave before reshingling
