I have three locations as a suggestion.<br/><br/>My first one is Bucharest.  Granted, it's not the US, but Eastern Europe, and that region in particular, have long been associated with vampires, and the legend of Dracula.  Normally, that would be vampire central, but given that the Black Court is destroyed and fragmented, I would say it would be an interesting study - who tries to fill the supernatural power vacuum left behind by the annihilation of the Blacks?<br/><br/>Second is Miami, for the reasons I originally gave - hot days, hotter nights.<br/><br/>Last is Las Vegas - lots of showy things, street magicians (both mundane and magical), and a whole lot of fun.
