Fifty years ago today, the National Park Service hosted a novel activities fair for Washington, D.C.’s lucky residents.

More than one thousand youngsters and their families participated in martial arts training, chopped and molded woodwork, listened and danced to music, and climbed through obstacle courses.

Held on the iconic and spacious White House South Lawn, even the First Lady participated in the memorable day’s fun and games.
