March 8th, 2010, at the Pamplonada Pirotecnia in Tultepec, Mexico.
From variablek’s YouTube page:
Chances are, if you’ve ever bought a firework in Mexico, it was made in Tultepec.
The local firework factories, families, and businesses build massive floats (approximately two stories tall) called toritos. They are made from paper maché and other materials in the likeness of a bull, covered completely and decorated with rockets, and painted up to look like any number of themes — chickens, dragons, Emiliano Zapata — there was even a Minnesota Viking torito.
…The evening begins with the parade of toritos through the center of Tultepec. Live music, singing, chanting (usually hyping up one firework company or another), and consumption of beer and pulche ensue.
…The parade ends as the sun sets, and one by one a torito will enter the center of the town square where throngs of people anxiously await chanting, “Fuego! Fuego! Fuego!” (Fire! Fire! Fire!)
