Why is "1937 National Scout Jamboree" trending?

Wikipedia Overview

The First National Jamboree of the Boy Scouts of America took place in 1937. Originally scheduled to take place in 1935 to celebrate their silver jubilee, an outbreak of polio in Washington, D.C. and the neighboring states, caused it to be canceled and pushed back, finally taking place from June 30 to July 9, 1937. Twenty-five thousand scouts attended the event taking place on the National Mall at the foot of the Washington Monument using equipment loaned by the United States Army. Scouts from all around the United States arrived by train, while representatives of several foreign countries' scouting groups traveled by boat and even by foot. The event was celebrated by the entire city with Federal buildings being opened for visits, Mount Vernon offering daily visits, and many local residents volunteering their time. U.S. President Roosevelt took part in the celebration and a special message from Lord Baden-Powell was broadcast from London to the scouts during the jamboree calling for International Friendship. It was a display of American patriotism with American flags on display; the event took place in the American capital in front of the White House during the week of the 4th of July.
