CNN reports that hundreds-of-thousands of Girl Scouts, former members and supporters swarmed the National Mall on Saturday for the organization's 100-year celebration.
The event, "Girl Scouts Rock the Mall", brought together scouts from around the world, organizers said, to watch performances, to participate in sing-alongs and other educational activities. Juliette Gordon Low founded the Girl Scouts in 1912. She was posthumously awarded the Medal of Freedom by President Obama last month.
The Washington Post has a fantastic photo gallery of the events. A few select pics below:
