Milwaukee area is great, wife and I live just west of town in Waukesha County in an area called "lake country" for obvious reasons. I'm from the Midwest so I've always loved the seasons, but she's from Houston and took a little time to adjust, but she loves it up here now.
In contrast to browndeere above, there are some parts of milwaukee county worth living in, but like anywhere, you have to know where you're at. We lived downtown milwaukee for a year before moving to the 'burbs and loved it - but we wanted space, a nicer house and the other benefits of living away from the city.
If you need any more info on the area I'm happy to help!
