The visitors began their tour in Washington, DC, on June 2, where they met with the sponsoring Highway Education Board and President Calvin Coolidge ("We desire to profit by your experience and I hope that you may profit by ours"). On June 3, BPR officials conducted the visitors on a tour of the experimental farm in Arlington, VA. That evening, they embarked on a tour of the States arranged by Chief Thomas MacDonald and S. T. Henry, Director of the Pan-American Highway Commission. In Illinois, the visitors see Abraham Lincoln's tomb in Springfield and inspect the Bates Test road, on which the Illinois Division of Highways and BPR conducted pavement tests (1920-1923).
