[2] Vardon tied for ninth place in the 1916 U.S. Open held June 29–30 at Minikahda Club in Minneapolis, Minnesota.

[3] He continued playing professional golf for four decades and became the oldest competitor at the 1930 U.S. Open at Interlachen Country Club.

He had been given four months leave from Royal St George's to work at the Onwentsia Club in Lake Forest, Illinois.

This was part of a deal that allowed Vardon to enter that year's U.S. Open held at Englewood Golf Club, New Jersey.

Pamphlets that survived the clubhouse fire at White Bear Yacht Club in 1937 record that although the original golf course design was by William Watson, there was further development by Vardon and Donald Ross.
