What were the affects of the Dust Bowl on Dick Coon and his businesses as noted in the nonfiction book, The Worst Hard Time?

Dick Coon owned most of Dalhart before the region began its decline. He owned the hotel and many of the shops in town. He held poker games at his hotel and always had a C-note in his pocket that he would never spend. In the end he lost everything and finally gave his C-note to a young cowpoke who couldn’t find a job.
