If we enter a comms blackout, make sure you are prepared. Know that while you may be excited, your family may be freaking the hell out. IF you may need to go find them, make sure you have physical paper maps and know where to meet.
You won't be able to just type that shit into your phone.
All my family is in one place for the duration.
If you have to move, be aware of all the back roads and streets, as main streets and highways might be jammed or closed. If you have a truck or 4-wheel drive vehicle, you might use old railroad beds and some cross-country travel through fields and farm lanes.
