On the last Wednesday of every August, the population of Buñol, Spain swells from its usual population of 9,000 people to 40,000-50,000 tourists who descend upon the small town with one goal in mind: pelting their fellow man with as many tomatoes as humanly possible.
39-year-old iReporter Jose Miguel Fernandez de Velasco captured the messy action at La Tomatina Festival on Wednesday, first from a town hall window, then down on street level.
In theory, there are guideline to ensure safety and sanitation: don't bring hard objects which may harm others, squish the tomatoes before throwing to lessen their impact, wear goggles to protect your eyesight, and don't rip anyone else's clothing. The two latter are generally ignored - but it's all in good fun.
After the last tomato has been thrown, fire trucks wash down the street with water from a Roman aqueduct. Participants, however, must rely on kindly locals with hoses or a dip in the Buñol River to rinse off the saucy residue.
