Given the question: Given the following context:  On November 30, 1928, whilst on tour in Cleveland, Beiderbecke suffered what Lion terms "a severe nervous crisis" and Sudhalter and Evans suggest "was in all probability an acute attack of delirium tremens", presumably triggered by Beiderbecke's attempt to curb his alcohol intake. "He cracked up, that's all", trombonist Bill Rank said. "Just went to pieces; broke up a roomful of furniture in the hotel."In February 1929, Beiderbecke returned home to Davenport to convalesce and was hailed by the local press as "the world's hottest cornetist". He then spent the summer with Whiteman's band in Hollywood in preparation for the shooting of a new talking picture, The King of Jazz. Production delays prevented any real work from being done on the film, leaving Beiderbecke and his pals plenty of time to drink heavily. By September, he was back in Davenport, where his parents helped him to seek treatment. He spent a month, from October 14 until November 18, at the Keeley Institute in Dwight, Illinois. According to Lion, an examination by Keeley physicians confirmed the damaging effects of Bix's long-term reliance on alcohol: "Bix admitted to having used liquor 'in excess' for the past nine years, his daily dose over the last three years amounting to three pints of 'whiskey' and twenty cigarettes.....A Hepatic dullness was obvious, 'knee jerk could not be obtained' – which confirmed the spread of the polyneuritis, and Bix was 'swaying in Romberg position' – standing up with his eyes closed".While he was away, Whiteman famously kept his chair open in Beiderbecke's honor, in the hope that he would occupy it again. However, when he returned to New York at the end of January 1930, Beiderbecke did not rejoin Whiteman and performed only sparingly. On his last recording session, in New York, on September 15, 1930, Beiderbecke played on the original recording of Hoagy Carmichael's new song, "Georgia on My Mind", with Carmichael doing the vocal, Eddie Lang on guitar, Joe Venuti on violin, Jimmy Dorsey on clarinet and alto...  answer the following question:  What town did Beiderbecke spend a month at in 1929?
The answer is:
Dwight
