||To celebrate AASHO's 25th anniversary, some 500 members have breakfast at Washington, DC's Raleigh Hotel, site of the association's founding. (See December 12, 1914.) In the day's highlight, AASHO President W. W. Mack presents Certificates of Appreciation to the 15 surviving founders, 9 of whom are present. J. E. Pennybacker, Jr., the only surviving founder from OPR, is present to receive his certificate. "As president of the Association," Mack says, "no happier privilege comes to me than that of presenting these certificates to the men who made highway history here 25 years ago."
