Heat and,drinking water, excellent! If the tent were relocated from the forest to the slope as some suggest, would the lack of these two things be a troublesome omission? Now, if tent was pitched in the forest, an outside cooking fire could be made, but if wood for a cooking fire was had, then why not also heat the tent? After all, this is a Russian winter. Camping on 1079 at elevation 880 has two important downsides, no heat nor hydration. Camping in the woods could eliminate those inconveniences. Yet, conspirators moving the tent to 880 on 1079 have this problem in staging the scene.
When the DP9 were in the woods at some point, they had stream water to drink. Did they boil it, drink it ice cold? Where is the kettle or cups?
