 In the years that followed O’Day grew, adding two hotels, shops, a newspaper, dwellings and in either 1887 or 1888 a post office, while also remaining codependent of neighboring Washburn concerning educational, religious and social life.The community of Washburn, formerly Keetsville, was officially incorporated as a town on August 4, 1880, though it is unclear if O’Day ever incorporated as a separate town.The two communities continued as separate entities through the 1880s and into the 1890s, when in 1892 the O’Day post office was disestablished and the Washburn post office took over for a newly consolidated community, a consolidation that was likely prompted by the building of a public school between the two communities.
