pretty much everything below -20 feels the same IMO
we used have these stupid weeks where everyday it would be around -35 ambient and then since it was Fargo and there is never a non-windy day the windchill would be something ridiculous like -70, but wind chill is kind of a "made up" entity, it doesnt really mean anything...the air temp is the same, it just describes the cooling ability of the air...so its no big deal
Im just happy to be living in a place where the teens are considered cold...I can deal with that
