Chicago Memorial Day Live
Many Americans observe Memorial Day by visiting cemeteries and memorials. A national moment of remembrance takes place at 3 p.m. local time. Another tradition is to fly the flag of the United States at half-staff from dawn until noon local time. One of the longest-standing traditions is the running of the Indianapolis 500, an auto race which has been held in conjunction with Memorial Day since 1911. It runs on the Sunday preceding the Memorial Day holiday. The Coca-Cola 600 stock car race has been held later the same day since 1961. The Memorial Tournament golf event has been held on or close to the Memorial Day weekend since 1976.Matthew Dennis, Red, White, and Blue Letter Days: An American Calendar (2002).
Sociologists, following the lead of Robert Bellah, often make the argument that America has a secular "civil religion" – one with no association with any religious denomination or viewpoint – that has incorporated Memorial Day as a sacred event. Our American tradition includes an obligation to honor the sacrifices made by our nation to earn our freedom. With the Civil War, a new theme of death, sacrifice and rebirth enters the civil religion. Memorial Day gave ritual expression to these themes, integrating the local community into a sense of nationalism. The American civil religion in contrast to that of France was never anticlerical or militantly secular; in contrast to Britain it was not tied to a specific denomination like the Church of England. Instead the Americans borrowed selectively from different religious traditions in such a way that the average American saw no conflict between the two, thus mobilizing deep levels of personal motivation for the attainment of national goals
