Key Largo, Fla. The palms grow shorter and scrubbier as we slice through Florida's low country, whizzing past citrus groves and palm farms where conveniently overlooked illegal immigrants earn their keep. We stop and go at the traffic lights of Homestead, cruising due south toward the Keys, the barrier- island necklace that spins off the southern tip of the state.
