It can be a difficult environment if you don't have a place to get out of the cold. The other day when this was photo was made the temperature during the night was less than -30 c. and -27 c at the time of exposure. When I was young -40 F/ c wasn't uncommon during the winter. (-40 is the same temperature in Celius and Fahrenheit) here in this city. At one time when I was young I had to work with animal hides at a temperature of -25 or -30 c they were like wooden planks with a shag covering also stiff. The skins had just come from an abattoir by rail.
