In Washington, DC, on Saturday, May 30, 1936, it was Memorial Day. (Originally known as Decoration Day, it was designated Memorial Day at the turn of the century. The National Holiday Act of 1971 declared the holiday to be the last Monday in May to ensure a three-day weekend for Federal holidays.) Helen and Dale went to Arlington Cemetery, below, and saw the gravesites of President Teddy Roosevelt and General Pershing.
