The Wisconsin State Fair opens today (Thursday) in West Allis, kicking off eleven days of agricultural judging, animal sales, music, rides, and food. U-S Agriculture Secretary Sonny Perdue will join Governor Scott Walker at the fair’s opening ceremony at mid morning. Perdue will then join state Agriculture Secretary Ben Brancel at the State Fair’s youth center in a noontime discussion about next year’s renewal of the federal Farm Bill. The fair has set attendance records the past four years, with total crowds surpassing one million each year. Tonight’s (Thursday’s) main stage show features Retro Futura — an ensemble that salutes the stars and hits of the 1980s.
