Below are some websites that may help with food prepping, i.e. building up a cache of food that will keep you, your family, and others fed during rough patches.
Readynutrition.com may sound like a plain food or cooking site, but it centers on prepping. Here is a grocery list on the site for a foundation of food preparedness for one person for six months. It also has a link to Mormon food prepping stores which also sell to non-Mormons. The food may sound boring (i.e. flour, beans, oats, powdered milk, etc.) but it will keep you fed. If you wonder why the list has so much flour and wheat, do you really think you will be able to go down to your local grocery store anytime and get a loaf of bread? We may need to rethink our daily lives.
Here is a general prepping site I have read over the years, covering all kinds of topics. There are many good ideas here, with lots of links.
Thirdly, here is an interesting site. An older couple is attempting to be as self-sufficient as possible, using their 5 acres in rural Pennsylvania. They have a lot of tips and links for everything from gardening to building a barn. Though they are in their 60’s, their energy level is amazing. One thing I’ve noticed in my own life, being in my 50’s and having lived in suburbs all my life, country living toughens you up.
Please think about preparing. Do what you can, and/or do what the Lord is guiding you to do, in whatever circumstance you are currently.
