Where a lot of residents came from.
No, actually, unlike the southwest US, most of the Hispanic residents here don’t come from Mexico (if you speak Spanish, you can tell from their accents.) They do however come from a LOT of other places:Cuba, Dominican Republic, Colombia, Peru, Panama, Costa Rica, Chile, Argentina, Uruguay. El Salvador, Honduras, Nicaragua... (not including a significant Haitian population).
The thing is as a local pundit once noted, everyone here drives according to the rules of their country of origin.
(Incidentally, I would point out that unlike the Mexicans, people from many of these places are more conservative; they did after all come here to get away from the Chavez’s, Ortegas, Kirchners, Correas, Morales’s etc of the world).
