Laugh it up.
Nothing really funny about history.
St Augustine Florida is the oldest continuously (European) populated city in the United States. And, as territory if Spain, it remained Spanish until 1763, just short of 200 years, roughly half of its existence.
So it's not unexpected that it might have a uniquely different population and culture.
I love St Augustine, but it is not exactly “South” Florida. It takes me five hours to get there from the “Deep” South.
