Milwaukee is a wonderful city, with plenty to do especially in the summer. Downtown is doing well, with lots of new condos, restaurants, etc. Lovely parks and beaches along the lake, festivals every weekend. It is clean, safe, affordable, and fairly friendly with midwestern values. Even the traffice is quite reasonable. If that isn't enough, downtown Chicago is a 90 minute train ride away.
I moved here from Detroit 13 years ago, and before doing so checked out the crime statistics. Even the worst areas have half as much crime as Detroit. (I don't want to disparage Motown. I worked in the city for 20 years and NOTHING bad ever happened to me or my co-workers. But by comparison, MKE is safer.) Especially if you are downtown or stay east of the river, you will be fine.
I teach nursing, and most of our new BSN grads have jobs. However, our program is higly respected, and they had a critical care rotation. Some just finished internships in critical care, and were offered jobs. However, the job market is tight, and ADN new grads are NOT being hired many places. It may take while, and I would line some thing up before moving here.
Good luck with your new life.
