When I was camping with my sis and her husband out in Minnesota last summer, we mistakenly left the cooler outside all night. Needless to say, our camp was raided by a fat, bear-cub sized coon that night. He made so much noise that I thought a person was in our camp. He had his head and whole upper body inside the cooler. The next morning we found that he had eaten almost everything, including the fishing worms, chocolate bars, sandwiches, hamburger, etc....
