So the one bright note to our surprise trip to Chicago was the windmills. On the way up to Chicago we discovered that Indiana has a giant windfarm just hanging out doing it's bit to save the planet. We also passed a school with a windmill and solar panels and what looked like some biomass energy stuff on some dairy farms. Cool, cool stuff.
Some people seem to think that windfarms are eyesores, but I can tell you that I thought they looked awesome.
