(You're not supposed to do this anymore in D.F., but oooooh ... just for old time's sake, like it's the year 2002.)
This is Parque de los Dinamos in southwestern Distrito Federal.
The bottom part where most visitors gather is not much. And like with other big parks on the outskirts of the city, there is a petty and sometimes-violent crime issue at los Dinamos that should be noted.
But anyway, it's the woods, it's the mountains, and in crowded chilangolandia, it's a sigh of relief.
Additionally, the pulques are good.
These are curados of piña con guarana and an apio. Both were excellent.
