I think Rush in in West Palm Beach, out on one of the barrier islands.
I'm pretty sure Rush's place is on Palm Beach itself, which is a barrier island. He lives there with all the super wealthy types, the Kennedys, Jimmy Buffet, etc.
IIRC, West Palm was actually founded so the folks who worked at Palm itself would have a place to live.
Anyhow, they will be on the strong side of whatever this turns out to be. Palm Beach is more at risk than West Palm, clearly.
