It seems logical to evaluate your most likely emergency scenario. Where we used to live - SF Bay area - it was earthquakes; where we now live I think forest fire would be our biggest worry. In an earthquake one's supplies oughtn't be in the basement (but who has a basement in earthquake country?); for forest fires, I'm not sure. What I have is in the garage. Worrying about "what ifs" if they really aren't likely (tsunami in Kansas) is a waste of effort.
My husband's cousin's wife grew up in East Germany (well, his cousin too, for that matter); Gina had a morbid fear of being caught without supplies. There was always a basket of food in the car when they traveled (even after the Wall fell, which is when I knew her). It was quite pathologic; I remember once that she would not go any further before buying a rotisserie chicken. The idea of traveling without food was terrifying for her.
