Jerry, I agree with your assessment of the immediate danger. This is nothing new.
Long term, our plans need to address how to handle the people leaving a strike area and living with a suddenly hyper alert government, military and police system.
Our own personal plans do include bug-in and bug-out situations, but I confess we are short on long term supplies.
If we had to leave the area, we (again my own immediate friends) would be needing to start almost from zero to build a survivable homestead. It would be a full year before a farm/garden could be a reliable food source, so the amount of supplies needed at the beginning is large.
We certainly know what we would need for this, but we are NOT there yet.
