I played around with Emergency Essentials Food Storage Analyzer, selecting items that I think Patrick and I would actually eat, and it was a lot of fun! It really wouldn't cost toooo much money to have a 30-day supply of food, but the plan is to buy something every week and transition into having a decent food storage supply on hand.
If food storage is something you are interested in, or are already doing, you should check out the analyzer and see the exact content and nutritional value, as well as how long it will feed you. Pretty stinkin' awesome! Have fun!!
