I'd actually rather be out at -20F than +30F. Once things have frozen, there's no risk of being cold and wet at the same time, which is harder to dress for than just being cold.

That's the real issue in Maryland and similar latitudes. We often alternate between sub-freezing and above-freezing temperatures. Snow falls, melts, and then accumulates in large puddles. Bonus: on a particularly cold night, the puddle freezes on top, and then you fall through.

I'm not trying to win some kind of misery Olympics. But mid-temperatures can be tricky to handle in ways that aren't obvious.
