See the little green sign on this building. The street signs are not on posts at the corner, but on a friendly nearby building. One can go seven or eight blocks without seeing a street sign. I've learned to count the streets or avenues to maintain my position.



Avenidas run east and west. Calles run north and south. Odd numbered to the north and the east of the central streets.

An unusual street sign. Easily seen and extant!
