Bugging means you had better have some place to go.
“Bugging out”? To WHERE??
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.
