When 'the balloon goes up", you have to make a decision to either stay where you are , or to go elsewhere.
It all depends on variables and your flexibility and ability to re-act in a timely manner.
If you have no where to go, fortify where you are (food, water, etc.)
If you decide to go elsewhere, you have a day to a day +1/2 to go and get there; after that,even the stupefied will have figured it out and accepted reality, and react.
If you are traveling, make sure you have enough fuel to get to where you are going; if you have only a half tank, make sure you can either make it, or enough to go back home.
I pray there is no TEOTWAWKI event. Should there be, I pray to be able to bug in. Two other choices: Travel to Spfld vacation home or if sold stay with sister’s kids, or go North about 15 miles and live off the land by the creek.
We have pickup and van usually full tank to bug out. Used to have a trailer, but sold it.
Bug out option is not good. Better to stay where we have food growing, trees for fuel, and good shelter. Even if house is storm damaged. Can camp in back yard, and salvage stuff maybe, at least we have lots of fruit and nut trees, and plenty of wood stacked for fire pit.
