Security should go along with that water you're storing. In fact, security is more important. Take a look at what happened recently in the earthquakes in Haiti and Chile. Heck, study any disaster where resources suddenly became scarce. Once the resources started dwindling, people started looting. It's human nature. You can have 100 gallons stored up. Unfortunately, your next door neighbor with a rifle is better equipped than you if you have no security. Your water and all your stuff become his stuff if he so desires.
