Traditionally, one grills burgers, drinks weak but very cold beer, goes to the beach or river or pool, sees a movie (I would suggest "Independence Day") or an outdoor concert, and watches a fireworks display.

Some folks also like to take their guns and fire some rounds straight up into the sky. However, this is generally acknowledged as A Bad Idea. In the West, firing off one's own fireworks is also considered A Bad Idea since this is fire season.
