Byrd..my reply went a bit astray,as some do.i look over the site late at night waiting for my pain meds to kick in so i can go to sleep..no big deal,just DJD in a knee.but as for long term storage i think the thing to do would be to make a big buy of your normal food and when you shop take from the front of the stored food and put the new in the back.if you want just a heap of food put away i would do the rice,beans,flour,canned meat,--so on, route.just looking around the web for camping food i have run across too many to count suppliers of all sorts food for long term storage.
as i'm sort of fuzzing out now i'll leave with an idea that just came to me..get a bread machine,i found a good one at a yard sale for $5,and set aside several ten pound bags of real flour and yeast packs.if the grid is down you can make bannock.
my only issue is short term wilderness survival so i don't get too deep into this subject.
