Based on things in the world and such, I am planning on making a mass purchase of some preps to try and firm up some holes we have. I am looking for some advice for a good and accurate calculator for figuring food stores for families. We are currently reviewing our stores and will use that list and the calculator to generate a needs list and go from there. One hole we have is defense, so I am going to pull the virtual trigger on a 10/22 rifle, as the ammo is cheap and effective on lots of critters that have 2 and 4 legs. Any advice would be appreciated. We cannot afford to do big projects such as solar, generators, etc., so we are focusing on bugging in and what we would need to survive for an extended period of time. Another tough subject I am looking for advice on is how to handle kin who live with us, but do not buy into the prep mindset regarding these prep purchases, since my wife's parents and one sister live with us, but again do not see why we do what we do.
