I was brought up as a poor country boy. Our family did all the old-fashioned methods of living. We heated with wood, canned food, did the garden and had a well, killed pigs/hogs, and had a cow for milk and butter. Oh yeah, we also had a two-seater for comfort and had that luxury until I graduated from high school. I still appreciate the information you try to get out to upper level folks. It takes me back in time.
Though its light weight and long shelf life are ideal for navigating harsh conditions, freeze-dried food is probably most famous as a cultural curiosity: Like many Americans, I discovered it in a museum gift shop, gawking at the styrofoam-like ice cream that astronauts used to have for dessert. More recently, I encountered it at a disaster preparedness convention in Raleigh, North Carolina, where smiling, gray-haired preppers manned tables piled with plastic bags full of vegetables, meats, and stews.
