if you haven't got a stocked out, secure bunker. literally don't bother making a "plan" just have some bottled water, tinned food, camping stove, fuel spare clothes/boots etc. you literally have no idea what you would be faced with, any plan will be useless and hopelessly naive. just have some supplies, and a weapon. it might be fine to stay at home, it might be home is engulfed in a firestorm they you need to flee. it might be your neighborhood organises together and you stay safe by working together, it might be your neighbor tries to kill you for a bottle of water.
