That's cold .. my first real cold was when i fell through some ice on a Yukon Lake (i had some casual work on a small oil drilling venture) .. then the coldest was on a Greyhound trip NY to Vancouver .. ...-70 windchill at a greyhound bus/truck stop somewhere about the great lakes https://investorshub.advfn.com/boards/read_msg.aspx?message_id=60381978 I still feel in terms of F. Have to convert all the time. LOL Ps, that -70 was by memory .. -40 without wind still rings a bell, .. could be a bit out ..
