The big show

Unlike backyard fireworks that happen pretty much completely randomly, major community fireworks shows take months of design and planning and require a host of people to pull off. A choreographer assembles the script for the show, and in most cases programs computers to execute the plan. The stagehands or crew carry out the directions of the production manager and choreographer and prepare to safely launch the fireworks. In some shows, an announcer will explain to the audience what is coming up. Finally, no show would be successful without the safety crew, whose sole job is to ensure that the fireworks are produced safely. These are the cities that have the most spectacular 4th of July fireworks.
