Mother Nature can keep that cold bottled right up there. Coldest I've ever felt was -25F in a deep freezer at a meat packing plant. And that was only for about 10 minutes. Can't imagine what it would feel like outdoors.
Up to 10° here. That's the "COLD" mark on my temperature. Above 10°f, everything is much more doable. Below 10° , it cold. Necessary outdoor stuff only.
Many years ago, we had pretty cold temps with wind chill of -50°. Nothing like that in recent memory........thankfully.
