+        Most Spanish street names begin with Calle officially
+        but since it's so common, this is often omitted entirely.
+        As such, for Spanish-speaking places with numbered streets
+        like Mérida in Mexico, it would be legitimate to have a
+        simple number like "27" for the street name in a GIS
+        data set which omits the Calle. However, we don't really
+        want to train on "27/road 1/house_number" as that's not
+        typically how a numeric-only street would be written. However,
+        we don't want to neglect entire cities like Mérida which are
+        predominantly a grid, so add Calle (may be abbreviated later).
