I suspect that a change has been made to the counsel regarding food storage. See here. It looks like the basic counsel is now to have a three-month supply, with longer term storage as more of an add-on.
I like this idea. I think it seems less intimidating. If that’s the case, people are more likely to do it. And better to have a three month supply than to feel guilty about not having a year’s supply.
(OK, OK, here’s the real reason I like it: we have about a six month supply. Now instead of being 50% righteous, we’re 200% righteous. Woohoo!)
