In this May 10, 2012 photo, an Interstate 90 billboard billing a bull's head sculpture as the world's largest sits at the edge of Porter Sculpture Park, in Montrose, S.D. The park’s signature piece is a 60-foot-tall Egyptian-style bull’s head that stares down Interstate 90 motorists as they head out to South Dakota’s Black Hills. Wayne Porter spent three years creating the 25-ton monstrosity out of railroad tie plates, dubbing it “The World’s Largest Bull’s Head” on a nearby billboard. (AP Photo/Dirk Lammers) less
