Opening Day for the Elkhart County 4-H Fair is set for Friday. Miss Indiana USA Mekayla Diehl is scheduled to make appearances at the fair during its 8 day run. She was crowned Fair Queen in 2007. Besides the fried food, carnival midway, concerts and ag exhibits, fair organizers are attempting to break a world record, by hosting the biggest ever food collection drive during a 24 hour period that starts Sunday and ends on Monday.
