Had a neighbor in the adirondacks whose holding there was an off grid cabin full of preserved food that he visited occasionally but that he maintained primarily as a refuge from calamity.
He had grown up in Germany, and his dad was a milk man. As soon as WW2 became imminent, his dad butchered and canned the two draft horses that pulled the milk cart, and the family lived on it through the war. His grandfather had done something similar to survive WW1. Tof the he food and sanitary products hoarding is probably a positive evolution away from our grasshopper culture of the past few decades.
