In Mexico City, there's typically been a military and civic parade. The observance was moved to the third Monday in November, a decade ago. This year, however, the actual day, the 20th, is the third Monday. It's a "Puente", a 3-day weekend and banks will be closed on the 20th. A federal holiday. The parade has historically run down Paseo de la Reforma from Chapultepec Park to the Zocalo. I've found the area bordering the Zona Rosa ... to be a good spot to observe the parade.

You make someone stronger when you help them a little, but you weaken them if you help them a lot. Uno hace más fuerte a alguien cuando lo ayuda un poco, pero lo debilita si lo ayuda mucho. ~ Buddha | Buda
