FRESH, HOT FRENCH FRIES. Hayes Farms, of Big Lake, provided a staggering amount of potatoes again this year at the Minnesota State Fair for Fresh French Fries - a vendor at the Minnesota State Fair known for its fresh-cut, gluten free fries. The Big Lake farm provides all the potatoes for the popular food booth. Inset photo: Grace Bugher is pictured near a pallet of Hayes potatoes on the state fairgrounds last week.
