That article makes me wish I had the cash to buy some rural land and bury a tractor trailer of food in it!!
Some items, like rice, need extra packaging. Put rice into a ziplock with one corner open and place the bag into the vacuum bag before sealing. Otherwise, the rice grains will puncture a normal vacuum bag.
Get into trucking and then at least you will have the tractor trailer. I hear the July weather makes the lot lizards quite tasty this time of year.
4 season gardens, stocked fish ponds, small inventory of livestock for personal level of sustainable food production, feed crops for the livestock. Add orchards an wood lots for firewood and extra food....etc.
A friend of mine has such on about 40 acres.
She gives away a lot of food to friends an neighbors. Produces bumper crops each year due proper planning an simple irrigation plans that are beneficial to property, plants, ponds an critters.
Lots of work for even her small farm. But her wise use of her property is educationally impressive.
