The State Fair of Virginia’s organizers plan to increase the event’s focus on agriculture. The 10-day fair begins Friday under a new ownership structure. The Virginia Farm Bureau Federation is now the fair’s sole operator. It previously owned 50 percent of the fair, and bought the remaining shares earlier this year. Farm bureau spokesman Greg Hicks tells the Richmond Times-Dispatch that new events include an educational display that teaches children how to raise crops and a guided tour of livestock competitions. Hicks says organizers expects 200,000 to 250,000 visits during the fair. That would be an increase from an estimated 160,000 visits during the 2012 fair.
