The Grand Prix Pinewood Derby was held Saturday in the activity center of College Avenue Church of Christ. Cub Scouts of all ages competed against the clock to determine the winner of each group. The cars cannot be wider than 2-3/4 inches wide, at least 7 inches long, and not weigh over 5 ounces. The cars are built by the Cub Scouts with some adult guidance. At bottom are the winners.
