Why is this exclusive House Concert a "Tropical" House Concert? Well because, climatically, Florida is divided into two regions. The tropical zone lies generally south of a west-east line drawn from Bradenton along the south shore of Lake Okeechobee to Vero Beach, while north of this line the state is subtropical. How cool it that!? Er, warm. Or hot! Ah, heck. It's just good, clean Floridian fun!
