As the 57th-annual 3i Show closed Friday in Garden City, the site of the 58th show remained uncertain.For decades, the farm show has alternated between Garden City and Great Bend. However, Eddie Estes, director of the Western Kansas Manufacturing Association which sponsors the ag exposition, has expressed an interest in finding a permanent home for the event. That may not be in either of the two communities.“It’s still up in the air,” said Jan Peters, director of the Great Bend Chamber of Commerce.
