Quite a dilemma as to how to deal with a future that has no precedent in recorded history, Wizard. I have undertaken a number of measures similar to your suggestions, but suspect this will be quite a learning experience for all of us. Your foresight will likely serve you and your family well.
As for chemtrails, they could complicate things immensely as food and water will be the critical commodities in the near future.
