I'd heard about this a few months ago (I live pretty close to where it's being filmed). What I find odd about it is that northern NJ is really just a suburb of NYC, & many people who live here are NYC transplants. So it seems like more of a repeat of RHNYC than a show about different regional lifestyles.
I'll probably enjoy it b/c I live here, but probably it'd be more intresting to see a RH Denver or RH Santa Fe instead of the same old same old.
