Please don't misunderstand my reasons for questioning, I am just curious. We don't have hurricanes here, or earthquakes. I also live in a farming community and we all have our own borehole for water, septic tank etc. I do keep some food in reserve, in the winter, in case the weather is severe, but nothing like one month's supply, let alone 6 months. We do lose our electricity sometimes, in storms, but we just manage with candles until it goes back on. We are never concerned about civil unrest. Even when I lived and worked in London, we were never afraid of house break ins or burglaries, although of course they do happen. Earlier in the year we had some riots in a part of London. There was quite a lot of looting I remember, but it all fizzled out, as the culprits were rounded up. I think preparation is a good thing on the whole as long as a person doesn't become obsessional about it. That would be very sad.
I don't think anyone misunderstood your questions. The only dumb question is the one that goes unasked. It's good that you have some supplies. You are better off then a lot of other people. You would be surprised at how many people shop day to day.
