Something I added to my go bag with my MREs and basic gear are a couple of the cheap plastic bowls, cups, and cheap silverware from Walmart, a tea towel and a little 4oz bottle of dish soap. It really changes my moral and mindset when I don't have to eat everything out of pouches and crackling water bottles for days on end.
HOW MANY CALORIES? calories are more important than price, because living in another state i can go to the same stores and get the same thing with a different price. THE CALORIES STAY THE SAME. And is much more important in an emergency.
