Proactive, not reactive. While I realize that not everyone is able to purchase or store vast quantities of tools, food, fuel, water, and etc., rudimentary equipment and provisions do not require that much space. Buy a little extra non-perishable food each trip to the store. Keep an extra "12 pack" of water on hand. The list could go on indefinitely, but the point is that the individual MUST be constantly vigilant about their preparedness status. Situational awareness is paramount in the grand scheme of things. If you develop the Ostrich mentality, that is to say living with your head in the sand, whatever your scenario is will not have a good outcome. By preparing for the obvious threats in our respective geographical areas, we will have most if not all the necessary provisions to deal with the sudden unforeseen happenings that occur. I guess the bottom line is don't wait until the excrement is in the ventilation to get what you need.
