Warren County Farmers Fair. The 67th Annual fair has something for everyone. Where else can you thrill to a hot air balloon ride, eat cotton candy on a carnival midway, view a variety of livestock, watch traditional craftsmen at work, get down-and-dirty in a Mud Bog competition, and cheer your neighbor on in a tractor pull... all in the same place? Visit the web site for a full list of activities and events. This year's fair again features the 4th Annual Balloon Fest, and the Traditional Arts Expo.
