Mangum Main Street opens 2010 Farmers' Market Saturday July 10th and will be open following Saturdays and Wednesdays at 9:00am. As it depends on the growing season the market has melons, squash, cucumber, peppers, and sweet corn. The market had six growers this last Saturday and others will be coming as their crops develop. Come early to the market. Over one hundred shoppers attended last Saturday to receive their Main Street Farmers' Market shopping bags.
