We actually had a few good old-fashioned arguments about the show Revolution over the weekend. One of the mechanical guys in our group was asking why people hadn't gone back to using steam power. LadyFox (civil-enviro) was more troubled at how concrete was simply just gone in certain places (i.e. O'hare). I said, I think I have it figured out. I bet all the engineers banded together and formed their own city where everything works just fine. Where they actually do have steam power, working sanitary systems, etc. Basically a fully-functional infrastructure. They are just waiting for the "others" (or people we see in the show) to find said city. We were all in agreement. LOL
