So if you don't die from breathing the ash and it turning into concrete in your lungs you will starve to death. Build up food storage.
Wheat is about $0.15/lb in 50 lb. bags from a grain elevator. You could have half a ton to store for $150.00.
A wheat grinder is either about $70 for a hand crank or about $275 for a good electric one.
Sam's Club for some big packs of yeast, cooking oil, salt, sugar, rice, etc.
Used 55 gal. poly water barrels are ~$30 each or so if you look around. Don't let starving be an option for your family.
The starving to death was a observation. I have been buying dry rice and beans along with other items that can be stored such as high quality tuna and other canned meats. I have several canisters op propane for my lanterns and they can double for a room heater by lighting them and keeping them on low and shutting off a room,(yes I know about airing out the room for fresh air periodically). I do need to get some water containers though. I have thoughr of getting the large ones that go on a trailer for spraying crops with and fill with water and collect rain water too. There are many thing to get prepared with because when TSHF there will be no electricity and no water.
