This live stream is at the Macy's 4th July fireworks:
New York City has the largest fireworks display in the country, with over 22 tons of pyrotechnics exploded. Other major displays are in Chicago on Lake Michigan; in San Diego over Mission Bay; in Boston on the Charles River; in St. Louis on the Mississippi River; in San Francisco over the San Francisco Bay; and on the National Mall in Washington, D.C.
Independence Day fireworks are often accompanied by patriotic songs such as the national anthem "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. 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 fireworks from less restrictive states.
The Hudson River is a 315-mile (507 km) river that flows from north to south through eastern New York. It rises at Lake Tear of the Clouds, on the slopes of Mount Marcy in the Adirondack Mountains, flows past Albany, and finally forms the border between New York City and New Jersey at its mouth before emptying into Upper New York Bay. Its lower half is a tidal estuary which occupies the Hudson Fjord created during the most recent North American glaciation over the latter part of the Wisconsin Stage of the Last Glacial Maximum (26,000 to 13,300 years ago). Tidal waters influence the Hudson's flow as far north as Troy.
