Fun and broad look into various infrastructural systems of NYC, with beautiful illustrations. Pretty inspirational in terms of "wow, there's a lot of cool, complex, and meaningful systems I could be working on!" Sometimes the explanations get a little muddled or the numbers don't quite make sense but I'm willing to overlook that as the broad strokes seem fine. It does feel slightly outdated - left me wondering what the current state of all these systems is.
Overall definitely worth the time - there's a lot in here and it is really a quick read.
