In his new book “Ways to the West” (Utah State University Press) Tim Sullivan embarks on a car-less road trip through the Intermountain West, exploring how the region is taking on what may be its greatest challenge: sustainable transportation. Combining personal travel narrative, historical research, and his professional expertise in urban planning, Sullivan takes a critical yet optimistic and often humorous look at how contemporary Western cities are making themselves more hospitable to a life less centered on the personal vehicle.
