I will quote my brother in Bemidji, MN - "There is no bad weather, only bad clothes" - or equipment (my addition). In -40C, I, too, would seek warm shelter, roasting chestnuts on an open fire along with agreeable company, etc. If circumstances dictated that I travel, I would. I would probably go with a liquid petroleum stove. You just have to have the right stuff (and knowledge/skills/capabilities)for the environment in which you are operating.. In other words, you must be equipped to survive.
