I have a couple of questions
1.) I agree that the best possible course of action for TEOTWAWKI  would be to have a retreat. Today you described how strategy’s like the “Batman in the Boondocks” approach, or “RVing” would probably fail. How does someone who does not have a retreat, (or the funds for one) plan?
2.) In your book “Patriots “, the main characters had formed a group years in advance. How does one find like-minded individuals to join groups such as theirs? Talking to your neighbors about things like this get you labeled as a kook pretty fast.
1.) If you cannot afford to buy a retreat, then perhaps you have some country cousins? Or a friend that owns a farm or ranch? Make some overtures to them about storing some grub and gear at their place. Assuming that they have acreage and outbuildings, offer to buy your own locking CONEX  to leave there (to stock with your tools and logistics), so that you don’t use up all of their available storage space. (Nor will have you have to worry about things getting used up, misplaced, or pilfered.)
2.) Your best course of action is to seek out like-minded individuals at your church or perhaps at your local rifle range. A seemingly casual but “directed” conversation can garner you a lot of useful info without tipping your hand. The key is to ask questions rather than expounding on your view of the future. Proceed with caution–and prayer!
