I get what you're saying, Frisket. Getting loved ones to buy-into the possibilty of things going south can be tough. Start talking about equipment and their eyes glaze over. Getting them to understand that they might have to leave the house because of a temporary localized event like a house/apt fire, train derailment, etc. should be easier. These things happen all the time. A kit like this would go a long way to making things more comfortable and it shouldn't invoke too many images of the tin hat brigade.
It's a good list that would be easy to modify for a family. In that case, lovies (teddies, blankies, etc.) would be a smart addition. Even non-prepper parents have been known to stock up on duplicates of these essential items for just-in-case. One left behind teddy and you'll never be caught without again.
