HARRISBURG, Pa. (AP) — Three of Pennsylvania’s professional sports mascots – including the Pittsburgh Steelers – are depicted in the Farm Show’s butter sculpture, an annual feature of the state’s massive agricultural exposition. The sculpture was unveiled Thursday, two days before the Harrisburg event formally opens to the public. This year’s sculpture, crafted from about 1,000 pounds of donated butter, shows Gritty, Swoop and Steely McBeam, mascots for the Philadelphia Flyers and Eagles, and the Steelers. This year’s Farm Show includes 12,000 competitive exhibits. It runs from Saturday through Jan. 11. Admission is free but parking in Farm Show lots is not.
