For 66 years the Grundy County Fair was located in Mazon. As the crowds became larger the fairgrounds was moved in 1971 to its current location north of Morris. The one-third mile paved oval Grundy County Speedway was built. A new breed of famous race car drivers circled this modern super short track. Names like Bobby Allison, Tom Musgrave, Ted Musgrave, Dale Earnhardt, Mark Martin, Paul Newman, Joe Shear, Johnny Benson, Tony Stewart, Ryan Newman, Danny Drinan, Jim Mahoney, Don Carter Jr., Susan Spencer and the list goes on. The stars of tomorrow are currently competing at the Grundy County Speedway every Friday night in stock cars and Saturday night in midgets. The Grundy County Fair has grown through the years because of the hard work and dedication of many people. The livestock and racing venues have evolved with each passing decade, keeping the spirit and excitement of “Going to the Fair” alive. The Grundy County Agricultural District Fair is proud and honored to have provided good clean family fun and to have been a part of our great American history for the past 100 years and looks forward to the future, with continued support to agriculture.
