This Friday, we're giving you a peek at Completing Our Streets: The Transition to Safe and Inclusive Transportation Networks by Barbara McCann. McCann is one of the founders of the Complete Streets movement, which looks to make streets friendly to everyone no matter their mode of transportation. It's this month's $3.99 special e-book, so if this teaser piques your interest, act fast! In this chapter, she talks about what inspired her to begin working for complete streets and why we keep building incomplete streets.
