New York City
If I had a billion dollars, I would move to New York City. The great thing about New York City is that it's easy to write about - and books about New York City sell very well, sometimes. Not that it would matter if I already had a billion dollars. Let's revise, then, and say that if I had a publishing grant of $200,000, I would move to New York City temporarily, and by writing about my experience in living there, I would make a billion dollars and move to New York City permanently.
