This year’s fair dates are Aug. 7-17. Conservation World, in the northwest corner of the fairgrounds, is open 10 a.m. to 7 p.m. daily. With 30 acres of hands-on outdoor activities, shows, demonstrations, learning opportunities, sensory hours, games, music, food, and shade, fairgoers will find themselves returning to Conservation World again and again.
