I know cold weather. I spent a year at the US Army's cold weather
test site at Ft. Greely in '73 & '74. It is at the bottom, between
mountain ranges with the cold air rolling down and a near 0% humidity.
The temperature was so low at times they wouldn't tell us at the radio
and TV station the exact temperature because they were afraid of causing
a panic. Those days all were were allowed to report was, "Be careful,
its cold out there today" Vehicles with battery blankets, lower
radiator heaters, dipstick heaters, and you still couldn't start some of
them. You were allocated 20A @120 VAC for the heaters, and you had to
put 10 weight oil in the transmission and rear end because the usually
90 weight was so hard it didn't lubricate at all. It was like chucks of
