For a different perspective: We relocated to MKE from LA in March and closed on a house in Shorewood in July. Coming through Atlanta, GA and Bowling Green, KY; I can say honestly that Milwaukee rocks. It's not perfect, but it's hardly the war zone that people make it out to be.
We regularly ride our bikes to and from downtown and out to 'tosa for beer gardens and events (4 beer gardens within a 4 minute bike ride), regularly walk to the lake and our local with our dogs. We found a great church community and through outreach regularly go into the areas people are afraid of and have yet to experience any ill will.
Granted, we spent a decades living in Europe, the middle east and southern Africa; so we aren't the sort to be scared by a city as quaint and overlookable as MKE. Some people carry that fear and skittishness within them, we have never had that problem.
We got a great house for a fraction of the price per square foot than we had in LA; twice the size, half the price - literally a quarter of the sqft price of LA. Petrol prices are laughable and our cost of living is very very reasonable. Decent opera, good ballet, local beer scene is stellar, restaurants are surprisingly good; for music and museums Chicago is only an hour away.
The hardest part for us is the lack of good local gun stores and ranges; and the shortened growing season.
