Cold is one thing - playing in LETHAL weather isinsane.
I would note that even the Army has limits as to when soldiers must ‘come inside’ in extreme cold wx. -70.
Doesn’t take much of a breeze to get that cold.
This was only -4, “felt like” -24 (I’ve never really been fond of the whole “wind chill” measurement, the temperature is the temperature the the temperature was -4... maybe it’s because I’m a sunbelter and “wind heat” when the temperature turns a minor breeze into a giant hairdryer... but I digress), definitely cold, definitely unpleasantly cold, but not lethal. Well OK I suppose a person completely unprepared and unequipped could die in it, but that’s what the equipment guy is for.
