You forget sometimes how big, 'urban,' and sort of permanently tucked away Colonia Roma is, despite its known evolution. In particular, I mean the farther reaches of Roma Sur heading toward Viaducto. It's like its own mini-city. Here I am with my friend Nuria, a resident of Roma Sur, checking out the current show at Border -- deceptively monochromatic paintings by Gustavo Abascal -- and then having a coffee at Border's new cafe-gallery-library space at 43 Zacatecas. They specialize in graffiti and street art.
