I commute (when in Florida) with a Dahon Speed 7 folding bike that I keep down there for just that purpose. It allows me to commute to/from the Tri-Rail station in Boca to the Tri-Rail station at Commercial and then To/From Work and occasionally go out for lunch. It also allows me to avoid renting a car and having to drive in a community where no one should be allowed to operate a motor vehicle...
