Seminole Nation since 1866, the Freedmen were supposed to share in all benefits. Their case was dismissed from federal district court, which said the Freedmen could not bring suit without the Seminole Nation's joining. Their appeal at that level also lost, and in 2004, the US Supreme Court affirmed that they could not sue without participation of the Nation. In the meantime, in 2000, the Seminole Nation voted to restrict members to those of one-eighth blood quantum, essentially those with documented descent from ancestors listed as Seminole-Indian on the Dawes Rolls. This excluded numerous Freedmen who, although descending from an Indian ancestor, had only a Freedman ancestor listed on the Rolls. The registrars had tended to classify all persons of visible African ancestry as Freedmen, even if the individual had Seminole ancestry and was at the time considered an Indian member of the tribe. About 1200 Freedmen were dropped from tribal membership rolls. Economic development and programs The Seminole Nation of Oklahoma operates three gaming casinos, three tribal smoke shops, three gasoline stations, and a truck stop, which generate revenues for welfare, education, housing and economic development. They operate their own housing authority, an alcohol and substance abuse program, a business and corporate regulatory commission, several family services, a food distribution program, environmental protection program, and social service programs. They issue their own tribal vehicle tags. In addition, the tribe administers their share of the judgment trust from the 1990 land claim settlement, from which members can draw for educational and other benefits. Their annual economic impact was $81 million in 2010. Tourism and recreation The Nation holds its annual celebration, Seminole Nation Days, on the third weekend in September at the Mekusukey Mission Grounds, to celebrate tribal heritage and culture. The event is free and open to the public. The Nation provides free concerts, carnivals, and cultural events with the featured performer on Saturday evening. Other events include an art contest, banquet, princess pageant, cultural events, parade, and sports competitions. Food, art, and craft vendors and demonstrators are also on-site. A free traditional dinner is provided. Estimated attendance is 10,000. The Mekusukey Mission has RV campsite facilities available year-round for a nominal fee. Also at the Mission are softball fields and a gymnasium, where tribal members hold athletic and cultural events year round.
