I ran across a cool article in the New York Times, "The Curious World of the Last Stop." While not exactly tied to sustainability in the workplace, it's a very interesting look at the world of public transportation. This article documents the NYT's survey of the end of each subway line (24 stops in total). The article is complete with descriptions, photographs, and interesting vignettes describing the experience at end of the line.
Don't miss the interactive photo gallery.
