Entering its 49th year, the American Thresherman Assn. Steam, Gas and Threshing Show in Pinckneyville, Ill., has become one of the country’s biggest shows. Held at the Perry County Fairgrounds, the summer show takes place the week before the Tri-State Gas Engine and Tractor Assn. show in Portland, Ind. The ATA also hosts a fall show in October that, while much smaller and more laid back than its big brother, offers plenty to see and do. With tractor pulls, sawmill demonstrations, harvest food, and many tractors and gas engines to look at, the ATA fall show is a great way to cap the summer show season.
