Agricultural students competed this morning in a relay of farm-related courses in the annual Ag Olympics at the Litton Ag Center. Teams rode in tractor tires, tossed hay bales, drove in nails, and pushed a teammate in a wheelbarrow. The last stop, pictured at left, includes the entire team, which must get on "skis" and make it across the finish line. Today, members were to dress in chore clothes.
