while most of these suggestions are good, there are many more possibilities that need addressing. If you are planning for a long term sustainable future without the dependance of modern society, you will need transportation(bicycle?), a mountain bike can take you off the beaten path. You will need seeds to grow a garden, you will need antibiotics(colloidal silver, oil of Oregano), you will need some garden tools or at least the tools without the handles. You can always find handle material in the woods. You definitely will need to boil your water for purification, especially if everyone is out there trying to secure water for their families. You will need a place not well known to secure water, or off the beaten path. When the utilities go, the worst fights will be at the local creeks, rivers, lakes and ponds. These will probably be the heaviest guarded places , and the most unsanitary. Without a sewer system, most sewage will run into the creeks and rivers. You can survive a while without food, but not long without water. If you are planning to bug in and fight, it would be best not to engage a hoard of people unless truly in a life threatening siuation. You can only hold off so many before they burn you out or find another way to get to you. Water, food, shelter and clothing in that order should be your priorities. Good Luck. rockhound
