Let me help me fellow Freepers. . If this worries you don’t wait until there is a line at Costco, when you finally get in the shelves will be bare. Go now and buy the items in bulk that you know you will use anyway. Buy only mouse-proof containers, and then store in plastic totes. Buy small ten pound bags of rice and beans and store those in 5 pound plastic buckets. Keep everything cool and dry. Next, AR15 and 100 rounds of 5.56 or .223. If you need more ammo than that you’re screwed anyway.
I’ve got all that stuff already...left over from Y2K.
