Independence Day is always filled with festivities, and one of the many 4th of July traditions that always hold true is fireworks.

The Fourth of July has been celebrated across the nation since 1776. But when — and how — did Americans across the country agree to commemorate the holiday with a fireworks celebration?

In Huntington Beach, some parade-goers staked out their prime spots before dawn today to watch the famed march down Main Street, this year celebrating 121 years. The event is dubbed the biggest Fourth of July parade west of the Mississippi River.
