OK, well, it seems that /t's weather system is warmer than mine, so it got me to thinking (uh-oh) maybe that should be a rating, too.
I mean, there's wind-chill, which is what the weather would feel like when you consider in the wind.
Maybe there should be a Canadian rating.
A CR.
So, the CR for -12F would be a balmy 22.
/t would be searching for the suntan lotion should the temps get to there. It's what the Canadians would feel like the weather would be if....

And, I suppose, we should conversely also consider using someone from, say, Florida. Maybe a Lil Lamb? Of course, the wool's gotta go, so, after we shave her down some, we hold her outside in the -12 degree weather, and then ask her what it feels like....
"And, what does it feel like, Lil Lamb?"
({({ chatter chatter chatter bbbbbbbrbrrbrbrbrrrrrrr chatter})})

OK, well, she's holding up her leg in a gesture....uh. I think the experiment is over.....
"somebody get Miss Lamb her wool...."

OK, well, that didn't pan out so good....
