I finally bought a container of survival food that will last for 30 years, they say. I've been thinking of opening it early and "practise" eating this type of food but have not done that yet. I bought it from the local Walmart which had a few stocked. I've been thinking about ordering more from MyPatriotSupply or some similar outfit. I think I might need 7 years worth of food. I have about a month stocked up in regular cans and packages right now.
