Flutterby™! : Nicaraguan Address System

I haven't had to deal with this yet, but it's conceivably in my future: Nicaraguan Address System.

Instead of street names or numbers Nicaraguans use reference points from where they start describing a certain address. There are many known buildings, companies, churches, or other reference points, which are used to get a general idea where something is located. The next step is to state how many blocks away the particular address lies from the reference point.
