I am not an avid Indy racing fan, but tonight on the news I saw a story worth mentioning. It's not going to solve the world's problems, but I do think that the Indy car program is setting a very good example - they are now racing "eco-responsibly". Evidently, the Indy cars racing the circuit this year are running on 100% ethanol and you can read more here, here and here (all different links).
At the very least what I think this move does is generate conversation and raise awareness about our ecological footprint which in turn will hopefully get more people thinking about changes they can make in their own lives. As our favorite frog famously lamented "It isn't easy being green", but at least now Indy Racing is making it popular!
