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. The week-long festival features music, parades, dancing, and fireworks. On the night before the tomato fight, participants of the festival compete in a paella cooking contest.It is tradition for the women to wear all white and the men to wear nothing. This festival started in 1952. Approximately 20,000 to 40,000 tourists come to the tomato fight, multiplying by several times Buñol's normal population of slightly over 9,000. There is limited accommodation for people who come to La Tomatina, and thus many participants stay in Valencia and travel by bus or train to Buñol, about 38 km outside the city. In preparation for the dirty mess that will ensue, shopkeepers use huge plastic covers on their storefronts in order to protect them from the carnage. source
