I read a great post at For The Mommas about hurricane preparation and the nature of couponers and having a stockpile. While I personally don't keep a large stockpile myself, having any amount of extra food for emergencies can be helpful not only for your family but for those around you.
Empty shelves at the grocery store, that is all you will find here in the bread, water and peanut butter aisles right now. I just got off the phone with someone asking if I had any spare peanut butter, because they cannot find any, anywhere. I saw my neighbor in the store and she needed toilet paper.
