Great post. Thank you very much. Your narrative is great because it comes from experience and not from an armchair outdoorsman.
I also like to hunt and I do it in Pennsylvania, but it is not near the conditions that you experiment in Alberta. The coldest I have ever been hunting is 6 degree Farenheit.
I would like to know if the only firestarting device you have is the Blast Match. How are the strike anywhere matches or the regular wooden kitchen matches or the book matches in those cold conditions you experimented in your neck of the woods.

Also do you just go for a day and return home or sleep in your car and keep on hunting the next day?

If you don't mind to give us a list of what you take with you in the woods in this kind of outing.

Thanks again for the wonderful narrative.!
