Oddly enough, the American Podiatric Medical Association is in favor of smart growth — hence, their survey of municipalities where people walk to work (including those who presumably walk to transit), or walk for exercise, or even own dogs or athletic shoes, which presumably go along with walking:

Arlington, VA
San Francisco, CA
Seattle, WA
Portland, OR
Boston, MA
Washington, DC
New York City, NY
Eugene, OR
Jersey City, NJ
Denver, CO
