Residents came out en masse Friday night for the opening of the Madison County Fair. Carnival rides will run throughout the weekend and the following week, as well as the Foggy Bottom Petting Zoo and the antique tractor exhibit. Fair-goers will pay at the gate, and the cost covers admission to the fair and for the carnival rides. On Saturday and Aug. 2-3, the cost is $12, and from July 29-Aug. 1, the cost is $10. July 28 is Family Fun Day, when admission to the fair is free, and the cost for the carnival will be $5.
