Change is in the air and we've got the numbers to prove it on today's show. At a time when tax revenues are declining and city budgets are strained, our first guest has a modest proposal that could produce big dividends for cities.  Joe Cortright is an economist for Impresa Consulting in Portland, Ore., and his latest work shows how profitable it can be for a city to be greener, smarter, and with fewer people living in poverty.  The full report is available at CEOSforCities.org

Plus, is Chicago the new New York?  We'll speak with Wendi Taylor-Nations of the global PR firm Porter Novelli about numbers that show Chicago may be a trendsetter, in more ways than just national politics.

And, how do you teach your children about city planning? Planetizen's Tim Halbur will be with us to discuss his new children's book:Where Things Are, From Near To Far
