“Two decades ago Sears topped the Chicago skyline, locating its operations to the world’s highest building, the 110-story Sears Tower. In 1992 Sears moved its 5,000 Merchandise Group employees out from the Sears Tower to suburban Hoffman Estates, thirty-five miles to the northwest. Sears’s new retailing headquarters, named Prairie Stone, is anything but a city skyscraper. Built on a former soybean field, Prairie Stone includes more than 200 acres of reconstructed prairie and wetlands. The highest building is six stories high.” (5)
