I have enough stuff to go about six months. If the SHTF, I want to be able to last until reasonable order is restored. I hope that after the first few weeks most of us will band together for mutual aid. Living in a rural environment helps a lot.
Almost everyone hunts but most have little ammunition stocked. I am stocked with thousands of rounds and the components to produce over 150k. Defending what we as a community have is prime IMO. And if things get bad, taking from those who cannot defend themselves is a last resort.
Defending is tough, not only is firepower needed, but security teams and lookouts. It is not difficult for a marksman to take out targets at 500 meters. Many here have portable radios so communication is taken care of.
In my case, the weak link remains fuel for the generators....I have three...one is the main, one is back up, one is a small 900 watt for charging batteries etc. I have 150-250 gallons of fuel and that will not last long.
