My wife's car was up for emissions testing this weekend. This because of regulation meant to ensure that our exhaust pipes are only letting out a certain amount of evilness into the world. So, I drove over to the next town where the testing facility was and sat in line for 22 minutes in that hot summer sun with the other 30 or so cars at any given time on both sides of me, in idle, as we waited to get the documented approval that we were doing our part to save the world.
