I think the main topic of the discussion is what is a good, long storing fat/oil to have stored and what foods post event would be helpful in keeping us healthy.
But, post event we will all have our own different specialty diets we prepared for and what we are able to harvest from our homestead and the wild.
Some will be eating a lot of fish, others deer or moose or bear, others wild birds and squirrels, and some will be living off their storage and homestead critters. Here in the desert maybe scorpions and jackrabbits, I suspect the deer and elk will be harvested away real quick. But I have a shotgun for pigeons and other wild birds in the area. It is almost impossible to eradicate pigeons.
