Canned goods are good for 10
Canned goods are good for 10 yrs.
Easy start is to buy an extra case of vegetables, dried fruit, peanut butter or tuna fish a week. Whatever is on sale. you will have a good supply of food in no time.
You can start canning and go with the 20 year freeze dried stuff, but I think it is just a lot easier to buy stuff at your local grocery store or Sam’s while it is on sale . Don’t make a big deal out of it. start small and build.
If you start talking about 40yr storage and those kind of logistics, you are probably better off getting guns and artillary and just taking everyone elses food. (just kidding) I plan on being one of the zombies, so watch out!
