If you happen to be roaming around downtown and Little Italy during the few hours this museum is open, stop by the see San Diego's first fire engine—a horse-drawn steamer—and other antique firefighting equipment. You've got hydrants, helmets, axes, uniforms, and a 9/11memorial inside a former working fire station. As in working firehouses, everything is polished to perfection, and volunteer firefighters are usually around to answer questions. Kids can climb aboard one of the trucks.
