The Macy’s 4th of July fireworks show attracts huge crowds to the city’s waterfronts every year, and there are always places saying they have the best views for the spectacle — and plenty of people claiming to know the secret spots.

Fourth of July fireworks will return Friday on NBC, PBS and CNN. The networks will air TV specials such as "Macy's 4th of July Fireworks Spectacular."

In the weeks leading up to the holiday, Gary Souza and around 60 fellow pyrotechnicans are focused entirely on finalizing the 49th annual Macy’s show. But they are not strolling along the Brooklyn Bridge where it will take place, nor are they balancing aboard one of the four barges in the East River that will supply additional launch points.
