Newscopy: "San Francisco's traffic became tangled up today when this 70-foot coast defense rifle was moved to Fort Funston as protection for the Golden Gate Bridge. This confusion resulted when one of the trucks towing the gun became tangled up in the tow cable. The monster weapon weighs 143 tons and requires 800 pounds of powder to fire a 2400-pound projectile approximately 25 miles."
