CHICAGO—Firefighters at the 111th Ladder Company stared in wide-eyed wonder Monday as local 3-year-old Jeffrey Sturges quickly pedaled past their station house on his bright red tricycle. "Tricycle!" shouted Fire Chief Robert Clark, who, along with his crew, pressed his face against the station window and waved excitedly as the three-wheeled vehicle made its way down the street. "Hi! Hello! Hi!" Unable to contain its enthusiasm, the entire first unit then suited up, jumped inside their fire truck, and followed Sturges down the block in hopes of hearing him ring his tricycle's bell.
