The fall festival was started after World War II as a "welcome home" event for returning veterans. In 1948, it was confirmed that more beef flowed into the Chicago stockyards from Warren County, Illinois, than any other location.
That made Warren County the "prime beef center of the world," and the Prime Beef Festival was born.
The current festival includes a princess pageant, a parade, live entertainment, amusement park rides, food vendors, a car show, demolition derby events, a cook-off, livestock events and auctions, and other activities for the whole family. For four days, the entire community (and thousands of folks from out of town) migrate to the park for a celebration with corn dogs, onion rings, fun rides and great times.
