I was in Grande Prairie, Alberta yesterday and I had to take this picture on my way to the airport.
It might be hard to see, but yes, that says -17. Standing outside for 2 minutes to get gas in the rental car was torture.
I guess we were lucky, it was -29 last Friday. I tried to look for the picture I took a little over a year ago when I was in Little Rock, AR. The temperature on the car there said 117.
Aaahhh, the pleasant experiences I have on the road sometimes :O)
