A celebration of the red — west mostly — began Thursday at the Clay County Fair & Events Center and will continue on the grounds, indoors and out, through Sunday. Last year, it was announced “The World’s Greatest County Fair” would be hosting the Red Power Roundup, celebrating the 100 years of Farmall. Attendees will have an opportunity to enjoy 750 vendors, as well as exhibitors, tours, seminars, a daily tractor parade, a variety of food services and more.
