I think we all "get it" by now. You use a tarp in Canadian midwinter conditions, with a stove and chimney, and this setup works well for you. If anyone here is saying that such a system doesn't work in those conditions, you are living proof that they are wrong.

We fully accept your experience as being absolutely relevant to all similar places, with similar low temperatures, similar tree cover, similar fuel availability, similar wind speeds and similar wind breaks. You seem to be a bit behindhand in noticing that these conditions do not prevail everywhere, or that other people might have valuable experience in somewhat different conditions from those you are describing.

To illustrate, here in Portland Oregon USA we sometimes have snowfalls as little as 3 or 4 inches which temporarily cause havoc to auto travel in our area. Outsiders from places like Alberta, Canada often scoff at how it could be that such a trivial snowfall could cause such immense problems. It is because they have never been here at such a time, in those conditions.

Our snow is often heavy, wet and quickly packs into ice in the roadbeds. Our city has many steep hills. Few vehicles are equipped with proper snow tires or chains, especially if the storm was not predicted, and even properly equipped vehicles can end up in a ditch, it's so slick to drive on.

My point: maybe your experience, valuable as it is, does not apply in every place and every situation, even if it looks the same to you. Maybe it is isn't. Maybe you have to have a different kind of experience to really appreciate the situation.
