Baby boomers - all 76 million of them - are turning 50. Soon they will face the question: Where and how do I want to spend the last 30 years of my life?

And just as they have dramatically altered every other American institution that served them as they moved through their life cycle, aging boomers will change cities.

Joining us this week are Paul Hodge and Maddy Dychtwald.
