The real money is out in Somerset County-Bedminster, Far Hils, Bernard's Township, etc. Also, very northern Bergen County. But they need drama, and you won't get too much drama there.
Bergen County girl here, and as I was reading through the comments I was thinking that the truly tacky Jersey housewives aren't the superrich Ridgewood/Englewood Cliffs* women but the ones who could barely keep up with the property taxes.
*Are Ridgewood and Englewood Cliffs still the ritzy-rich areas? I haven't been home for a while. Usually when I think superrich NJ I think of Alpine.
