The use of Santa Isabel does indeed seem to be an error. I see, though, that San Felipe, like Santa Isabel, is part of the Mexicali municipality; San Felipe may also use U. S. rules. The "northamerica" file's quotation of the relevant decree mentions "los municipios de Tijuana y Mexicali" but only "la Ciudad de Ensenada" (rather than "el municipio"); we may get to use the largest city in the Ensenada municipality that's south of the city of Ensenada. That seems to be Rodolfo Sánchez Taboada (Maneadero) (22,957); the normal 14-character limit would suggest using Maneadero; it seems to have a larger population that San Felipe (16,702). Lázaro Cárdenas (16,294) is substantially farther south and thus likelier to use Mexican rules; some 14-character-limit creativity would be required. Of course if we were lucky we'd discover that Santa Isabel actually uses Mexican rules.-S --ado https://en.wikipedia.org/wiki/San_Felipe,_Baja_California https://en.wikipedia.org/wiki/Ensenada_Municipality
