Photos: Wisconsin State Fair's future

Calvin Marks walks his pig Parsley through spectators in the swine barn Tuesday at Wisconsin State Fair Park in West Allis. According to State Fair Park board chair John Yingling, the barn needs to be updated so animals do not have to be walked through the crowd. Marks is from Watertown.

Fairgoers photograph a Ferris wheel at State Fair Park in West Allis. Before this year, the site of the Ferris wheel was the west market, which was razed by the park because the space was underutilized.

Fairgoers mill about near the Ferris wheel at State Fair Park. The old west side market has been taken down, replaced by a splash of asphalt that is now the temporary home of the Big Wheel, North America's largest traveling Ferris wheel.
