If you remember a drawing of Ania... Lena again, one of my OC's but on the other side of the line 9 of the metro in Mexico city. I use this line daily to transport from the office to home: from Tacubaya to Pantitlan, the Brown Line. It is one of the most saturated and from 6pm until 10pm it gets too full. At the station Pantitlán and Apricot stations was made a movie starring Arnold Schwarzenegger the Governator: "total recall"

The subway in Mexico City is a great option for transporting it by car is a bit complicated. A part that is very cheap: USD$0.25
