*From Wackypedia* ~ "Of the 50 largest cities in the United States, Milwaukee has the second-coldest average annual temperature, next to that of Minneapolis. ... The 1982 event, also known as Cold Sunday, featured temperatures as low as -40°F (-40°C) in some of the suburbs as little as 10 miles (16km) to the north of Milwaukee, although the city itself did not approach such cold temperatures." So, you weren't toooo pampered. 😱
Yes, Zorkis can be used as warming devices. I place each on top of the wood stove for 30-45 minutes prior to need. I personally use Zorki.1s in my socks and my Zorki.4 in my cap. (I also have a couple of Chaikas coming for the mittens.) Cheers! 😉
