Patchwork Nation: Brand Identity

Each week in October, Dante Chinni, project director of Patchwork Nation and author of Our Patchwork Nation: The Surprising Truth About the "Real" America, reviews the way Americans group themselves into categories like "Boom Towns," "Tractor Communities," and "Monied Burbs."  Today, he looks at what the presence of Walmart, Starbucks, and Whole Foods stores in says about different parts of the country.
