There was also a show on PBS where 4 (or so) couple were challenged to survive the a year in Alaska all on their own. It really showed you what Grok had to go through in the winter. It was very hard for these people to catch and preserve enough salmon to make it through the winter. They tried to hunt, many of them were unsuccessful, even with rifles and a guide. One group even took to scavenging meat from a fresh kill they happened upon. What I didn't know at the time, and I don't think they did either, they should have taken the bones from that kill to get the marrow.
They had cabins, wood stoves, canning supplies, axes, saws, rifles. They were well equipped, and really struggled. Poor Grok!
It's grandma, but you can call me sir.
