 Chinameca is much like any other small town in Mexico. Cinderblock homes painted in bright hues. The aroma of marinated pork hanging in the air. I'm here for the town's fiesta patronal, or annual saint's day party. Every town in Mexico has one. It's not unlike a country fair in the U.S. There are carnival games and a ferris wheel, and even one of those swinging boat rides. But there's also something else.
