The American Camp Association (ACA), formerly known as the American Camping Association, is a 501(c)(3) nonprofit that serves the United States. It is an association for camp owners, camp professionals and others interested in summer camps and similar camp programs.
ACA runs an accreditation criterion for camps. According to ACA, to become accredited, camps must meet up to 300 health and safety standards. The accreditation process is voluntary, and ACA currently accredits more than 2,400 camps nationwide.
ACA also hosts a consumer oriented website for families looking for a camp experience for their children.
Additionally, the American Camp Association has 24 local offices  throughout the country. For example, the American Camp Association- New York represents one of the largest networks of camp professionals in the country with over 500 members representing over 300 affiliated camps.
The American Camping Association® (ACA) was founded in 1910 under the original name, Camp Directors Association of America (CDAA). CDAA was founded in 1910 by Alan S. Williams. Founder Alan S. Williams created a model and standardizing influence for the organized camp experience for the young. The CDAA merged with the National Association of Directors of Girls' Camps in 1924 and changed its name to the Camp Director Association (CDA). In 1935, the name was changed to the American Camping Association, Incorporated (ACA). This name would stay the same until 2004, when it was changed to the American Camp Association®. 
The Gunnery Camp is considered the first organized American camp. Frederick W. Gunn and his wife Abigail operated a home school for boys in Washington, Connecticut. In 1861, they took the whole school on a two-week trip. The class hiked to their destination and then set up camp. The students spent their time boating, fishing, and trapping. The trip was so successful, the Gunns continued the tradition for twelve years.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
