Input: Question: What year was the city founded where there was a walkway collapse in 1982? Passage:While visiting his parents for Christmas at Fort Riley, Kansas, in 1975, Atkinson found a job as a newspaper reporter for The Morning Sun in Pittsburg, Kansas, covering crime, local government, and other topics in southeast Kansas, an area known as “the Little Balkans” for its ethnic diversity and fractious politics. In April 1977, he joined the staff of The Kansas City Times, working nights in suburban Johnson County, Kansas, before moving to the city desk and eventually serving as a national reporter; in 1981, he joined the newspaper's bureau in Washington, D.C. He won the Pulitzer Prize for national reporting in 1982 for a "body of work" that included a series about the West Point class of 1966, which lost more men in Vietnam than any other Military Academy class. He also contributed to the newspaper's coverage of the Hyatt Regency walkway collapse in Kansas City, Missouri, for which the paper's staff in 1982 was awarded a Pulitzer Prize for local spot news reporting.
