I am not referring to the planet, although that is also (and always) true.
I posted before about the temperatures on
December 15 and
this past Tuesday.
This morning I saw a thermometer reading -22oF/-30oC.
However my car, a '95 Ford Escort, was still able to start. There was a bus waiting at the Park-and-ride, and it stopped downtown across the street from a Skyway entrance. So my total exposure to the weather was probably under 5 minutes.
I just checked the forecast. It may be a full 17oF/9oC warmer when I go home!
