San Miguel de Allende, Guanajuato, Mexico: El Dia de los Locos, or "the Day of the Crazies," is a carnival during which groups in 4 different neighborhoods in this historical town dress up and dance in the street in honor of San Pasqual Bailon, the dancing saint. More than just an excuse to party, for some it is also an act of devotion. 6/15/09 (photo: Ann Summa/Getty Images).
