The comms piece I am completely lost on; have to admit it out in the open. I am not certain what I should be looking for. For instance, my wife works approx 5 miles from me as the crow flies. What should I look into so she and I can have something in a pinch/emergency that I can assure her I am getting to her and we are getting home? What can we store in our cars/bags? (and what would have the best battery life?)
As to the purifier, I have stop gap measures to get us home including the water straws. At home, we have well water on a hand pump in case electric is out.
Thanks for the post...More for me to think about and act on.
Food for thought, establish a meeting point at a certain time, maybe 2 or 2 places. AKA a rally point. Maybe you and her can meet halfway so you both won’t have to walk too far and wait long to re unite.
Make sure her route is secure so as to minimize danger to her.
My 2 cents.
