I believe a lot of Old Florida remains. In person and in spirit. The ornate Venetian Pool in Coral Gables, built to attract settlers in 1920s, is still open to swimmers. There are still banyan trees in Coconut Grove, mangrove swamps on Key Biscayne and the Stiltsville community planted in impossibly blue-green Biscayne Bay. If you get off the turnpike and interstates while driving to and from Miami, you still see Old Florida.
Vast cattle ranches.
Overstuffed, tacky souvenir shops. Weather-beaten bait and tackle stores. Black canals and palm trees. Post-war neighborhoods of stucco houses and corbels streets. And there remains many of those homegrown roadside attractions.
