My local subway stop--Plaza Italia on the D line--is already incredibly useful. For 70 centavos (about 23 cents), I can get to my doctor's office in Recoleta, my mall (although it's hard to admit I have a mall, I do), or even the teeny tiny chinatown in Belgrano. According to today's paper, there's good news stirring underground. The gov't is planning a new line (dubbed the F line--just like my old LES local) connecting my Plaza Italia to 12 more stops, ending at Constitution (now just on the C).

Habrá subte directo de Palermo a Constitución
Construyen la línea F y extienden la E
