The BSA National Jamboree is a gathering, or jamboree, of thousands of members of the Boy Scouts of America, usually held every four years and organized by the National Council of the Boy Scouts of America. Referred to as “the Jamboree”, “Jambo”, or NSJ, Scouts from all over the nation and world have the opportunity to attend. They are considered to be one of several unique experiences that the Boy Scouts of America offers. The first jamboree was scheduled to be held in 1935 in Washington, D.C. to celebrate the 25th anniversary of Scouting, but was delayed two years after being cancelled due to a polio outbreak. The 1937 jamboree in Washington attracted 25,000 Scouts, who camped around the Washington Monument and Tidal Basin.
