Replying to Tell me about a Midwest, Finland, or other COLD places

So, I live in the Canadian rockies. It's rad here. We have big mountains, prerty good parks, OK snow, and pretty gnarly terrain. Whatever. It is about to get really goddamn cold for the forseeable forecast. Around -40. That happens once or twice a season. It's about to get so goddamn cold that most locals won't go up to the hills. Snow becomes velcro, rails get crazy sticky and landings are really goddamn firm.

All that said, I've heard it's really cold sometimes in Finland or the Midwest sometimes. What do you do there? Do you just say fuck it and go to the hill? Are there other options? How do you keep your feet warm?

Big ups to the real cold places.
