The DuQuoin State Fair is officially underway. The theme of this year's fair is a love a fair. It's the perfect theme for one couple, who is celebrating their wedding anniversary. Not only that, they have also been running a concession station at the fair for decades.For 35 years, Jim and Joanie have been serving hot dogs and burgers on homemade buns. They go together like ketchup and mustard."This trailer is pretty small," said Joanie. "We have to get along. It's too hot not too!"They'll be married for 52 years on Monday.Jim says the secret to longevity in his marriage is communication and it doesn't hurt having a skilled baker for a wife."If you love what you're doing and you love the person that you're with, why in the world would you want to go anywhere else," said Joanie.
