Some believe that an annual cemetery decoration practice began before the American Civil War and thus may reflect the real origin of the "memorial day" idea. Annual Decoration Days for particular cemeteries are still held on a Sunday in late spring or early summer in some rural areas of the American South, notably in the mountain areas. In cases involving a family graveyard where remote ancestors, as well as those who died more recently, are buried, this may take on the character of an extended family reunion to which some people travel hundreds of miles. People gather, put flowers on graves, and renew contacts with relatives and others. There often is a religious service and a picnic-like "dinner on the grounds", the traditional term for a potluck meal at a church.
