402 Norris Ave. - Completed in 1922, the Hotel Keystone was to represent the Can-Do-Club, whose endeavor was to "pursue the organization and completion of a new hotel to expand the commercial attraction of downtown McCook." The Keystone's glory days lasted for 40 years through the Depression, dirt storms, wars, motel development, and location of Interstate-80. However, by the early 1960s, the Keystone was on its last leg as a hotel, eventually becoming retirement living quarters to survive. 

After a few failed attempts by others, the McCook Economic Development Corporation secured $4.2 million from grants, sales tax income and backing by local banks. The Keystone Business Center is now home to several business, organizations and even a Co-Work Space - maintaining its original purpose to "expand attraction to downtown McCook."
