Roosevelt wanted to personally talk to people and give an account of his previous term in office. Mandan was one of five stops in North Dakota. He spoke from a stand erected on the north side of the depot especially for the occasion.

The rail line out south of Mandan was under construction and was completed the following summer despite heavy infestation of mosquitoes.
