Edward Ruscha is the census-taker of these voids that swallow the city. It is through his parking lots photographs that we perceive that they are a potential sewer. These terrains vague are indication that the real estate activity, at the moment, is not strong. They are negative spaces that remain in suspension (especially if the hemorrhage extends itself to the neighboring batches) until new dynamics occupies them and the zone reappears in other points. The metropolis is the increasing tide of the nondifferentiation. 

Here the interval takes everything, in a spreading occupation movement of the space. It is as if the space freezing under this entropic rigidity blinded all its possibility to coat any clear pattern. The city tries to resist the entropic proliferation, at the same time that produces it.
