 until midnight, August 8th through the 17th, except for that last night where we'll be closing at 9 p.m. Well, that's Mindy Williamson with the Iowa State Fair, who says the last Sunday grandstand show is a kids' bop concert at 6. Admission tickets will not be sold after 7 on that last night. Williamson says vendors will appreciate the earlier wrap time. Some of them go on to other fairs. A lot of our rides do the same.
