True. But when we were off campus, say in the place where we were in Disney's backyard, I was able to portal myself all the way to that Earth's version of China and back, no problem. In the silence monster world, I portaled Carol and I to Mexico where I found one the main meteor crash site that brought the monsters from space. So hypothetically, I ought to be able to open a portal to take us to this world's version of New York, or London, or wherever.
