Replying to Where Should I Move

So I've been given the opportunity of a lifetime. I've been interning for a big corporation for a couple of years now. Earlier this week my personal liaison who is a pretty high executive within this company told me that I would be receiving a job offer at the end of the summer and that it would be for whereever and whatever program within the company I wanted. I was told I had until July first to get back to him with my decision. I can basically go to any major US city because there are literally offices everywhere for this company.

So NSers where should I go?
