Uriel Montiel, 12, helps his parents operate rental mechanical rides called “flying chairs” from Holy Thursday through Easter Sunday at a religious fair at the Plaza de San Matías in Iztacalco, an administrative subdivision of Mexico City. People participating in the Catholic tradition of visiting seven churches during this time come to the plaza for food, pastries, games and rides. “I like to come because they let me get on the other games for free, but I don’t like the lack of sleep,” Uriel says.
