From July 26 to August 4, the Boy Scouts of America will celebrate their 100th anniversary! About 40,000 Scouts have convened for their centennial jamboree at Fort A.P. Hill near Fredericksburg, Virginia. There are plenty of outdoor activities at the jamboree–canoeing, rocket building with NASA, robot building with Lego, and mapping and photography tips from National Geographic!
