Preparing for catastrophic or short range survival is extremely personal and most of us keep it tight to our chest. I think PowderKeg says it best – Invisible and then Nuttus who knows that not all of us are the same skill or wherewithal stage, yet as a TEAM we shore up each others weaknesses, learn off each others strengths and it is a continual building process going forward.
Again, the reason we tend to look sideways at those who get a little too into prepping for an apocalypse is because of their smug optimism. People actually being realistic about a dangerous future would be better served joining the military or ingratiating themselves with high-level government officials than agonizing about a little mouth scuzz or foot fuzz, right?
Say you're at work and a terrorist attack occurs. Roads are closed to any and all traffic but you only want to get home - even if that means walking. You may not want to grab your full on family pack in the car or you may not even be able to get to it. But you just want a light kit to get you through. How far is it to get home from wherever you may be? This get home kit should provide for 1-3 nights of traveling on foot till you make it home.
