There's a newspaper that Sussex County prints with local apartment listings. You can pick it up at the Quick Check in town. They never have great stuff (you know how this town is) but if your study needs something quick, there might be a listing that suits his family and him.
i found my apt thru the star ledger. in fact, i called in reply to the online ad, and it hadn't been printed in the paper yet! (got in before everyone else)
