WCNJ

A t-shirt from 89.3 WCNJ in Hazlet, New Jersey.  Couldn't find a whole lot of info about the station although it appears they carried an Oldies format at one time.  Comedian Jim Florentine's Wikipedia entry says that he was a DJ there and that it was a college station but I couldn't find what school it was affiliated with.  Anybody have more info about WCNJ?
