Apparently anyone that's anyone is living out in Palisades, New York. Björk Gudmundsdottir (better known by just her first name) was selling her home there last year, and Al Pacino, Mikhail Baryshnikov, Harvey Keitel are (or have been) residents. Oh, and Didi Conn—who you know as Frenchie in Grease—is now selling her home there. The NY Times reports that the home, once owned by Bill Murray, has about 5,000 square feet on about 2 acres, and Conn and her composer husband are asking $2.9 million.
The real selling point: "Mr. Murray left a vestige of himself behind: a fireman’s pole from the Ghostbusters movies still connects two floors in the garage." Or as this listing puts it: "Separate garage with guest quarters/studio built around original Ghostbusters fire pole." Sadly, no listing sites actually have this magical place pictured.
