Prominent Americans in diverse walks of life, from filmmaker Steven Spielberg (who helped launch a merit badge in cinematography) to adventurer Steve Fossett to U.S. presidents, were BSA members as youths. Over two-thirds of all astronauts have had some type of involvement in Scouting, and eleven of the twelve men to walk on the Moon were Scouts, including Eagle Scouts Neil Armstrong and Charlie Duke. The pinewood derby—a wood car racing event for Cub Scouts—has been declared "a celebrated rite of spring" and was named part of "America's 100 Best" by "Reader's Digest".
