I have lived in Florida for over 10 years. The best All Year living is in the North East. The Best Snowbird Living is a little further South, probably anywhere South of the Cape. It does get a little chilly here in the winter, it was 72 today but does get cooler at night. But not for long. It is hot in the summer too but nothing like South FLA.
I agree with all the not so good comments on SWFLA, and anywhere North of Sarasota is too congested and overcrowded.
We like our little town, has everything we want and need and nothing we do not. A little south there is reasonably priced water property on Salt Water Canals with access to the Intracoastal.
Those who live and like West & SWFLA please stay there, and encourage others to join you, it is way too hot for us and just too crowded to do anything leisurely without trying too hard. Plus every business thinks you at a tourist an nickels and dimes you to death. As mentioned, great to visit.... once a year, DW likes to go shelling... Swimming in the Atlantic is much nicer than the Gulf too. Central Florida is just unbearable in every way.
