Yesterday as I put all the new goodies into the inventory spreadsheet and checked to see how long that would last me (as
@Neb would referrer to a Man-Years) I came to the conclusion that if I/we can eat it before it goes bad it is not hoarding, so I guess anything up to a 5 year supply could be "reasonable"
The funny thing is that if you build a "reasonable supply" for 7 people and then 5 of them move away you could end up being a little "over supplied".
When our kids moved out there were some fresh foods that we always had too much of because we had not adjusted our "family" size in our minds when we would go shopping. With one kid it was bread, with another it was milk......
Now day's I assume that one of the children would return in a SHTF event, so they are included in our target setting "family"...
