Volunteers have returned after operating the Kalona Chamber of Commerce booth at the Iowa State Fair.  The chamber has represented Kalona at the fair for nearly three decades. Cheese, fudge and jelly made in Kalona were among the products they sold. One of the volunteers manning the booth was Brian Strasser. He says the Kalona Bakery’s cinnamon rolls were one of most popular items among fair goers. Around 1,000 were sold each day.
