Preparing Makes Sense. The likelihood that you and your family will survive a house fire depends as much on having a working smoke detector and an exit strategy, as on a well - trained fire department. The same is true for surviving a terrorist attack or other emergency. We must have the tools and plans in place to make it on our own, at least for a period of time, no matter where we are when disaster strikes. Just like having a working smoke detector, preparing for the unexpected makes sense. Get ready now.
