There was a time, many years ago, when we were ice-fishing on a 3 day weekend. Whilst out in the mountains of B.C. there was a cold-snap. Went down as low as -48 on the thermometer. Actually had to light a controlled fire (in a steel 5-gallon oil can) underneath the engine block and baby/maintain that for a few hours. Sleeping bags draped over the hood, just to hold in some of the heat.
I've driven in Canada Winter's all my life. Been off the road a time or two due to one reason or another. Out of all that though, I've only ever been blown off the road by the wind, once. Makes for interesting times.
Drove 2 hours on a closed highway in my '80 Monte Carlo. I found it interesting that there was nobody on the highway at all, though things did get dicey/washy a time or two. It wasn't until I reached my destination where I came upon the RCMP road-block preventing travel. I just waved and continued on into town.
I thought it was rather comical though, the line-up of 4x4's, highway tractors, big/bad equipment and whantot,,, and then there comes me in my 2-door sedan with speakers sticking up outta the trunk just nonchalantly sauntering by....
