Educating children from America’s cities may be the toughest challenge urban leaders face. This week, we’ll talk to three guests who are deep into meeting that challenge.

Indianapolis Mayor Bart Peterson is the nation’s only mayor who has the power to charter schools. His point person in setting up and running the chartering operation is David Harris who is with us this week. David and Mayor Peterson have been recognized for their efforts with an Innovations in American Government Award.

Irasema Salcido is founder of the Cesar Chavez Public Charter Schools in Washington, D.C. The schools use each subject – even music — to teach public policy. We’ll find out from Ms. Salcido and music teacher Emily Isaacson about life inside a charter school.

Finally, Smart City will feature the latest in city travel from Keith Bellows, editor of National Geographic Traveler.
