Lack of aspersions. Your city is what you want it to be. My campaign city is a per planned city that would have benefitted from geomagnetic lay lines if it hadn't gone so wrong; a failed utopia essentially.
Also, if it's your city you can put it anywhere. We already know where Chicago and Miami are, but Loothaven, TX, home to more robberies per capita than anywhere else? That's where you want it.
