This city is Olavarría, in Argentina. When I saw the map it remembered me immediately to the typical design of a city in the Sim City, and seemed to me to be very funny. It seems to have be constructed thereby intentionally jejeje.

A much bigger map, here (http://www.olavarria.com/archivos/servicios_al_viajero/mapas/imagenes/plano_olavarria.gif).

When I see that, I can't help but think of the red salamander-monster. I miss it.

any pics of the city?

perfect gird
