Can't find it. It's possible that what I'm thinking of is that with wind chill the temperature was down to 0 or thereabouts - but I do very specifically remember the TV talking about it being 0.
That's probably where I screwed up, trusting anything said on TV.
I'll agree that -20f would probably beat the holy crap out of anything that we experience over here. I'll also agree that it's quite possible that my personal opinion of humidity being the real killer is quite subjective, and open to interpretation.
And no, I don't think you're being a jerk. :)
