Getting out ahead of time

[River Song]

quicker repercussions?

Unless we have a meteor strike, or sudden nuclear/emp attack then there will be some warning for those "who have ears to hear and eyes to see". even if its only 48 hours or so.

As an earlier post by Morblanc said, bugging out would involve a well developed BOL.
In my present situation its going to be Bug-In with the children and relatives returning home.
