Cant help you with all the rest but I was able to get my wife "on board" by letting her simmer on ideas for a while. For example, "Honey, I am worried that if the power was out for X amount of time, how would we get by?" and "you know we have insurance if the house was get damaged, how would we make do if the insurance did not take care of things for a few days...." It worked! Now my wife has her own bug out bag (BOB) and an emergency kit / mini - BOB in her vehicle. Worst case scenerio - everyone thinks your a paramoid ecentric.
