Campaigning by horse and buggy, Gordon Clarke, running for alderman in Scarborough's Ward 12, hands a pamphlet to his neighbor Aubrey Crowhurst, who owns the horse, My Lenny Boy, and the buggy, an antique built by the McLaughlin Carriage Works. Clarke lives in a century-old farmhouse off Meadow-vale Rd. West Hill. He's also using a mobile home in his campaign. Advance polling in city and boroughs will be tomorrow, next Thrusday and next Saturday.
