From the Packsacks of a Computer Science Teacher in Northern Canada
=== by Bob Sutherland ===
Hello and welcome. This is a hobby website I started as a retirement project. It is a way of sharing some of the materials I collected in my packsacks during many years of teaching in Canada's remote northern communities. Now I am branching out and adding new content based on other sources of inspiration. There is no unifying theme. It is just a haphazard collection of web pages that I hope someone will find interesting or useful.

- What happens to vehicles when the temperature drops to -40 degrees Celsius? The simple answer is they freeze, break and tend not to work.

I have then tried to keep them operational throughout the winter as temperatures sometimes dropped below -40 degrees Celsius. Here is a description of my experiences.
