All, thanks so much for the comments. We wrote this up so long ago; it's really interesting to get feedback now. FWIW, The Infrastructure Observatory is working on more tours like this one, mostly in the NYC area. If you want to get involved (or have an idea for a tour that we should organize), get in touch at http://infraobservatory.com http://infraobservatory.com or @NYInfraObserve on Twitter. -Spencer
