A krewe (pronounced “crew”) is a social organization that puts on a parade or ball for the Carnival season. […]
Krewe members are assessed fees in order to pay for the parade or ball. Fees can range from thousands of dollars a year per person for the most elaborate parades to as little as $20 a year for smaller clubs. Criteria for krewe membership varies similarly, ranging from exclusive organizations largely limited to relatives of previous members to other organizations open to anyone able to pay the membership fee. Krewes with low membership fees may also require members to work to help build and decorate the parade floats and make their own costumes; higher priced krewes hire professionals to do this work. Parading krewe members are usually responsible for buying their own throws such as beads and coins, which are thrown to parade spectators according to tradition. Some krewes also have other events, such as private dances or parties, for members throughout the year. Some also make a point of supporting charities and good causes.
