New Jersey governors have been inaugurated in Trenton at least as far back as January 20 1863, when Democrat Joel Parker took the oath of office in the State House. Neither the state Constitution nor state law require an inauguration ceremony, but that hasn't stopped New Jersey's governors from cutting loose. Jon Corzine's 2006 party was held at Princeton University's Jadwin Gym. Chris Christie's first inaugural soiree was held at the Prudential Center in Newark. And Christie has announced that his second inaugural celebration will be held at Ellis Island, the gateway through which million of immigrants to this country have passed.
