Most people today are shocked to learn that back then Hialeah was almost all redneck.
Correct. Its amazing that when I lived in Boca (1991-1994) and Miami (1999-2002) I never once heard a southern accent, nor saw any rednecks until I drove north and got into St. Lucie County. Even in the latter county, they were way outnumbered by transplants (which is why they stood out).
