Fireworks are a constant feature of Mexican life (there are some banging away overhead as I write), and the pieces de resistance are always the Castillos, giant towers thirty or so meters high, covered with spinning wheels and crowned with a fiery cap which takes off to fly across the sky and ultimately land several blocks away. As the crown measures a couple of meters across, and the same high, you need to make sure you are not underneath when it lands. In Mexico, no one can sue or get compensation if one lands on their head, as bad luck is still an accepted legal reality. Here a couple of workers make the final connections to tonight’s version celebrating Allende’s Birthday.
