Mason Street
From Futurepedia, the Back to the Future Wiki
Mason Street was a street in Hill Valley. Biff Tannen's house was located at 1809 Mason Street, where he lived with his grandmother, Gertrude Tannen.
Mason Street ran north and south. On the morning of November 12, 1955, Biff walked north toward town so that he could pick up his car at Western Auto, and Marty McFly followed him covertly. Along the way, Biff took a ball away from some children and threw it on to the roof of a house.
