Girls Scouts of the USA turns 100 today! When I think Girl Scouts, I can't help but crave Girl Scout Cookies. But for many women who grew up as a Girl Scout, Girl Guide, or Brownie, the organization's name brings back fond childhood memories. Scouting began in 1907 in Britain, with Girlguiding in the UK founded soon after that, and the Girl Scouts of the USA launching in 1912. There have been some famous women involved in Girl Scouts, including former Brownie Kate Middleton, who chose The Scout Association as one of her charities, and who's covering the latest issue of Scouting Magazine. See how the youth movement has evolved over the years and some of the celebrity connections now!
