For the experienced prepper, there is comfort in knowing that you have plenty of food, water and supplies to get you through for the short term. You have candles, flashlights, batteries and light sticks. You have a extra blankets and the means to cook without fuel. And of course, you have a bug-out bag.
But imagine a scenario where a disaster is brewing and you have a bit of notice. There is a possibility, however small, that you might be stuck indoors and in your home for two weeks, possibly longer, without access to common services such as power, sanitation systems, and access to the local supermarket.
