Boo York is a thriving city populated with ghosts instead of humans and is home to the Peoplebusters. The Statue of Liberty is replaced with that of a witch and the city looks more like a giant demilitarized zone. The Ghostbusters, minus Winston Zeddemore, traveled to Boo York after they were sucked into the Central Park Twister.
