Yes, my folks retired to Cape Coral, having bought lots from the Gulf Development Corporation while they were still living in Maryland. It's a pretty sordid corporate story (they bulldozed all the trees and drained the swamp and sold to northerners) with the corporation also paying for those...
The series holds up beautifully because it's entirely character oriented and the writing is fantastic.
The final season also included episodes in Cape Coral, Florida, by the way, which was a new community being developed by Gulf.
