The great urban theorist Jane Jacobs wrote about cities of "exuberant diversity," and in our 2008 Cities of the Year, Chicago and London, we have two stellar examples.

These hot spots, these Fast Cities, are full of life and bursting with diversity -- in race, in culture, and in business. Join us for a tour.
