On July 6, 2007 revelers welcome water thrown from a balcony during Pamplona, Spain's 2007 San Fermmn festival.
Traditionally on opening day thousands—dressed mostly in white and donning red handkerchiefs—spray sparkling wine on another, while residents throw water on the revelers from balconies to cool them off.
Festivalgoers, visitors spend most of the night drinking wine and sangria—a wine, fruit, and lemonade mix. Pamplona, the capital of the winemaking province of Navarra, is situated east of Rioja, one of the world's most renowned wine region. (map of Spain)
