Go read John D. MacDonald’s books, especially the Travis McGee series. He paints a pretty good picture of the Floridization process.
“The further North you go, the further South you are.”
I’d say the above poster … is close. Living in way South Florida (called SoFla by the nits on TV), I’d say “the South” starts somewhere in Palm Beach county, but it gets thicker/heavier the further north you go. I personally find Tampa way too Southern for me (of course I’m a mixed race liberal hippy chick who was raised in Texas of all places).
South of Palm Beach county is a mixture of Latin cultures, Carribean cultures, and retired white people. A recent poll showed that intolerance of each other among the three groups is as high as ever.
