Just got back after a visit of 10 days to Sunshine/Lake Louise. Was there
for that cold snap that they had, the temp dropped to -40 C. All we could do
then was to shop or find a hot tub, but the temp soon rose after a day or so
to a reasonable -20 C. Did experience a wind chill of around -38 on one day
but as we were wrapped up it wasn't too bad. Just layer up, don't expose
more than you have to....
