100 degree heat with an air cooled engine

Kinda beat you all. I was in Antarctica in February this year. 'Rode' around in an open sled towed by a tractor at ~20mph. It was -26 outside, with wind-chill I don't know what it calculated at.

-26 Celsius or good old Fahrenheit? Makes a big difference; if C, that is a hot spell for that locale. Gets colder than that in the midwest.

Up to 70 degrees F of frost and more are not unknown in the Yukon. Spittle freezes solid before it hits the ground.

70 degrees of frost is -38F or -39C.
