Idling -- ARRRGH!

I noticed this last year -- people idle their cars in the winter. For hours. The parking lot at the grocery store was a disgusting cloud of fumes today. I could understand it (maybe) if it was -50C out, but it was only -8C! I mean, you barely even need to warm up your car at all in that weather! And it certainly isn't going to konk out after a trip in to get groceries. Especially a grocery store that less than 10 (short) aisles! On the plus side, it was only -8C today!

Don't even get me going on recycling -- but I'll save that for another day.
