I started storing staples like flour, rice, beans, pasta, sugar, salt, etc. I got 10 of those 5-gallon buckets and Mylar liners and filled them all. My son helped me vacuum seal the mylar bags and then the buckets are air tight. Supposedly they will last for 20+ years. I need to order 10 more. I've started buying some of the dehydrated and freeze dried staples in #10 cans too. I buy extra coffee when there is a good sale.
I learned how to do canning and one of my requirements for the small retirement house I am looking for is that there be enough yard for a good sized garden. I just want to be self-sufficient.
