La Tomatina is a food fight festival held on the last Wednesday of August each year in the town of Buñol in the Valencia region of Spain. Tens of thousands of participants come from all over the world to fight in a brutal battle where more than one hundred metric tons of over-ripe tomatoes are thrown in the streets.

Approximately 50,000 tourists come to the tomato fight this year, multiplying by several times Buñol's normal population of slightly over 9,000. In preparation for the dirty mess that will ensue, shopkeepers use huge plastic covers on their storefronts in order to protect them.
