It wouldn't be the Fourth of July in New York City without the annual Macy's fireworks show, which made its debut in 1976 to commemorate the nation's bicentennial. The iconic display will return to the East River this year; fireworks will be set off from the Brooklyn Bridge and from barges in the water below. The best viewing spots will be from Brooklyn Bridge Park and the Brooklyn Heights Promenade, and along the east side of Lower Manhattan.
