 The YMCA of Cass and Clay Counties and the Fergus Falls Area Family YMCA are officially united. They're now called the YMCA of the Northern Sky. Last month, the Fergus Falls Y told WDAY the merger will give it more time to focus on programs for members and spend less time worrying about hiring and administrative issues. YMCA of the Northern Sky is a name that could be used for virtually any Y in our region.
