Sounds good as part of a home food reserve. My guess is they are irradiated foods - foods exposed to enough radiation to "cold-sterilize" the food. Most of that kind of food has a very long shelf life, retaining nutrition without need for refrigeration.
Game is so plentiful here in South Dakota that I'm more inclined to stock up on fruits, vegetables and carbohydrate sources.
Which just triggered a memory of a fall drive through the Fort Randall dam area. My jaw dropped, there had to have been hundreds of thousands of migratory waterfowl there that day. They filled the skies, the fields and the water. I don't know what congregated them all in that area but it was an awesome sight.
I have a daughter. I tell her, "911 is what you dial after you're raped. 1911 is what you should have before they try."
