I went to Canada's winter carnival a few years back. There is a lot going on but one is a canoe race through the ice choked St. Lawrence river. I recall them wearing spiked shoed to climb over ice flows.

I stayed one night in an ice hotel. Absolutely beautiful lit up by LED lights and with ice sculptures. It was pretty cold by my SO couldn't sleep as it was -10f, She said when she closed her eyes she thought, "don't fall asleep, you will freeze", so we bailed. They provide the sleeping bag/liner and instructions (no cotton pajamas etc..)

Cold can be very dangerous though, because hyperthermia makes you not think clearly about what to do next.

One thing to keep in mind - should anyone find themselves sleeping in a very cold situation - is to eat significantly more than normal, particularly fatty foods (butter!). In the cold, your body uses a lot of calories to keep your body temp up and eating a dense meal right before bed goes a long way to your overall comfort.

I also have a belief that keeping a hot beverage ready-made in a thermos (tea or just hot water) should be considered a safety item when winter camping, sea kayaking, etc. Warming yourself from the inside is more effective than trying to throw on extra layers.

You can enjoy this in Europe too. With a sufficiently cold winter, you'll get a nice bunch of ice roads between Estonia and Finland when the Baltic Sea freezes up. It sounds pretty awesome.

OT, but what will happen to them after global warming? I guess its not too different than what happens during summer times.

This is actually a serious problem. Cheap shipping seasons are getting shorter for the remote North [1].

Madmen. You can run from or fight violence. Can't outrun cold.

In my mind, if a lake is that frozen, we're in a war against nature.

I know you’re joking, but you can - you know - literally outrun the feeling of cold in most situations.

You’re really cold? Eat. Run. Increase your insulation.

It's better than being too hot. At least if you're cold you can add clothes. If you're too hot there's a limit to how naked you can get!
