Here are some of the good things about Janesville, WI. First, they have pretty much what you need in life from a Grocery/ Hardware store, restaurants, etc. It has a lot of variety for being a 63,000 population. Another thing positive about Janesville is that they offer a lot of parks within or near city limits. Excellent place to start for the active family. Majority of the people living in the city of Janesville are really nice people and crime rates are usually low compared to others.
Here are some negatives about Janesville, WI. First, the city has become this "forgotten" city since the GM Plant closed in 2008. Another disadvantage is the local business. If your the " buy local" type of person, you might want to skip this city as an option. A lot of chain restaurants make up Janesville.
If their was one thing to change for the city is to bring the local business to the area. I would like to live in this city but many people leave Janesville because their is not anything in the city that has their career.
