Dimmitt, the county seat of Castro County, is on U.S. Highway 385 fifty-five miles southwest of Amarillo in the central part of the county. In March 1890 the Bedford Town and Land Company, headquartered at Sherman, in Grayson County, bought a section of land near the center of the county and laid out a townsite. H. G. Bedford handled the sale of lots at the new site, which the promoters named for their colleague and Bedford's brother-in-law, Rev. W. C. Dimmitt. During 1890 other promoters, including Ira Aten and Lysius Gough sought to develop rival townsites as candidates to be county seat. But on December 18, 1891, Dimmitt was elected.
