In this episode of the Bridge Builder, we speak with Tim Carney, author of "Alienated America: Why Some Places Thrive While Others Collapse." After traveling the U.S. to answer that question he now shares his data and research, which shows how a lack of social connections in communities are leading to their collapse, and the solutions he sees. Plus, we examine how our culture of alienation is playing a role in mass shootings.

In the mailbag, we examine measures aimed at curbing gun violence.

We round out the show with a fun way for you to start learning more about our state government while also learning some great Minnesota history.
