While home for a visit with family and friends Trevor Harper of Edmonton decided to try his luck with a metal detector on the lawn of Great Lakes Secondary School. "It's nothing to get rich on but it is fun and keeps us busy," he said of the treasure hunting he does with son Justin, 16. Here, Harper holds up a five-year volunteer service pin from the former Sarnia General Hospital that he found along with several coins, while his father, Allan, looks on. Glenn Ogilvie
