After holding the press conference in the Memorial Building on the afternoon of June 27th, the president traveled to Grandview where he briefly visited with his mother. Then he traveled back to 219 North Delaware and rested a bit and prepared for a dinner that the Mayor of Independence, Roger Sermon, hosted in his home at 701 Proctor Place with former officers of the 129th Field Artillery. Harry Truman had served as Captain of Battery D in the 129th Field Artillery in World War I in France.
The president arrived at the Mayor's home at 6:15 p.m. where he was greeted by a throng of Independence well wishers on the front lawn. Truman's military aides, Harry Vaughan and James K. Vardaman, accompanied him on the trip.
At approximately 7:00 p.m. the president went inside the Mayor's home where he had dinner with the officers from the 129th Field Artillery. Some of those in attendance included Edgar Hinde, J. Leonard Reinsch, Ted Marks, James Pendergast, and C. C. Bundschu. The entourage also included Charlie Ross, the President's press secretary and presidential aide, Matthew Connelly.
The president then traveled to the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS) auditorium to address his hometown. The event started at 8:00 p.m. and the president spoke around 8:30 p.m. in the auditorium.
