I go down there fairly often. It is very expensive to live in the Keys, and it can be pretty trashy/touristy in places. Not many who live there and work in the service industries can afford to own thier own home, so you have a good percentage of lower socio-economic types who are willing to put up with high cost of living just to be down there. There are a lot of bums and weekend drunks down there, too. You can't really leave rods, reels and gear unsecured very long before it will disappear. It is great fishing and diving on reefs, off shore Ocean side and on the Gulf side too. If ocean side is too rough you can always do something gulf side. The Marquesas and Dry Tortugas are not all that far from Key West either. Bimini and surrounding cays, just 55 miles or so off Miami is pretty fantastic too.
