More than 660 local letter carriers will participate in the nation's largest one-day food drive this weekend, the Stamp Out Hunger food drive. As they deliver the mail, letter carriers will pick up more than 100,000 pounds of food to provide to children, families and the elderly suffering from hunger. Put out your donations by 7am, or stop by the Reasor's location in Jenks or at 21st and Yale between 9am-6pm, as well as at Arvest Bank locations.
