Hi Chisel,
You make some great points, I think the fact that you are taking your future and the future of your family in mind is a great thing. Seems like you have also thought it out quite well. There was a magazine in the early 80's called 'Survive'; the early issues were very family oriented and until it was bought out by Peterson Publications (1983 or so) it was top notch. After Peterson's bought it, it became the single-guy-macho-survival-with-weapons publication then went under. Sometimes back issues can be found on EBay. Another good one is the older (late 70s - late 80's) Mother Earth News, very family oriented and many articles written by self sufficient, single moms. It is an outstanding publication and many of the articles are available online for free.
