Skiing in the cold.

Just curious, but we all ski in different places. Me if you haven't taken a hint, ski in Manitoba (It's all I got and it kinda sucks. It's the crap the east coast guys laugh at) We don't have nothing to big or too exciting here, but we do have alot of cold, and it friggen suck. An average ski day is about -15 Celsius, and the weather is usually a dick and it seems to more often than not drop down to -25 to -30. The coldest I'll ski in is about -25. I'd keep going, but beyond that, bandannas, bellaclavas or whatever just frost up and stick to your face, and my fingers start to hurt like hell. So reply to this with where you ski, average cold, and coldest you can ski in, make sure to say if your using Celsius or Fahrenheit.
