“On the afternoon of July 5, 1983, three adult supervisors and a group of youngsters set up camp at a popular spot beside Lake Canimina in the fragrant pine forests of western Quebec, about eighty miles north of Ottawa, in a park called La Verendrye Provincial Reserve. They cooked dinner and, afterwards, in the correct fashion, secured their food in a bag and carried it a hundred or so feet into the woods, where they suspended it above the ground between two trees, out of the reach of bears.”
