Out driving in North Carolina in what are seemingly "traditional rural" settings in the middle of nowhere I'll often come across signs reading "llanteria" (tire shop) or "Iglesia Evangélica" (Evangelical Church) in Spanish. At this point immigrants have reached most parts of the southeast U.S., rural and urban. BTW if you're ever in Hickory, NC there's a great Hmong restaurant with the hilarious name Duck 'n' Good Food.

EDIT: spelling
