Fireworks

Customs

Originally entitled Yankee Doodle, this is one of several versions of a scene painted by A. M. Willard that came to be known as The Spirit of '76. Often imitated (or parodied), it is a familiar symbol of American patriotism.
Independence Day, the only holiday that celebrates the United States, is a national holiday marked by patriotic displays. Similar to other summer-themed events, Fourth of July celebrations often take place outdoors. Independence Day is a federal holiday, so all non-essential federal institutions (like the postal service and federal courts) are closed on that day. Many politicians make it a point on this day to appear at a public event to praise the nation's heritage, society and people. Speeches and editorials may invoke American Revolutionary themes such as the founding fathers (including John Adams, Thomas Jefferson, Patrick Henry, and George Washington), the Constitution, the Liberty Bell, and democratic principles such as liberty, freedom, equality under the law, inalienable rights, and representative government.
Families often celebrate the Fourth of July with a picnic or barbecue, and take advantage of the long weekend or off-day to gather with relatives. Decorations (e.g., streamers, balloons, and clothing) are generally colored red, white, and blue due to the colors of the American Flag. Parades are often held in the morning, while fireworks displays occur in the evening at various places, such as public parks and casinos.

[edit] Fireworks
Independence Day fireworks are often accompanied by patriotic songs such as "The Star-Spangled Banner", "God Bless America", "America the Beautiful", "My Country, Tis of Thee", "This Land Is Your Land", "Stars and Stripes Forever", and, regionally, "Yankee Doodle" in northeastern states and "Dixie" in southern states. Some of the lyrics recall images of the Revolutionary War or the War of 1812. While the "1812 Overture" refers to Russia's defeat of Napoleon, it has been traditionally used by the Boston Pops and broadcast nationwide on PBS, so many Americans also associate this musical work with the July 4th fireworks.
"The Star-Spangled Banner", the USA's national anthem, commemorates the United States flag that was visible by the light of the rockets' red glare, the bombs bursting in air. This view of the flag through a night of bomb bursts inspired the captive Francis Scott Key during the War of 1812, and provided hope for the United States as it defended Fort McHenry.
Firework shows are held in many states, and many fireworks are sold for personal use or as an alternative to a public show. Safety concerns have led some states to ban fireworks or limit the sizes and types allowed. Illicit traffic transfers many firecrackers from less restrictive states, showing that the American people have nevertheless found a way to celebrate "with pomp and parade, with shows, games, sports, guns, bells, bonfires, and illuminations."
Most fireworks shows in the United States end in an intense finale, with a volley of fireworks rapidly launched almost simultaneously. Major displays are held in New York and Boston harbors and on the National Mall in Washington, DC. Detroit, Michigan, and Windsor, Ontario, also host one of the largest fireworks displays in the world over the Detroit River each year to celebrate both American Independence Day and Canada Day during the Windsor-Detroit International Freedom Festival.
