1. Attend the military parade that runs along the Champs-Elysées. Though it is often ignorantly bashed in the U.S., the French military is in fact one of the world's most elite, sophisticated, and technologically-advanced fighting forces. Check out their equipment, their soldiers, and wave after wave of jaw-dropping fighter jet and helicopter flyovers.

3. Not in France? Eat at your favorite local French restaurant. Many will probably be offering special deals on drinks and/or food in honor of le 14 juillet. For example, Napoleon in DC is offering free Champagne!
4. Watch a French or France-themed movie. I like Marie Antoinette for the French Revolution preview, or Casablanca for the rousing, German soldiers-drowning out rendition of La Marseillaise. You'll be shouting "Vive la France!" in no time.
5. Wear red, white and blue. If you're an American, it's possible that you have plenty of clothes in these colors hanging around from the recent Independence Day celebration. Get some additional use of of them by paying hommage to the drapeau tricolore.
Joyeux Jour de la Bastille!
