Of the several scenarios in the Prepper EOTW event list, there are some which imply the need to bug-out in a quiet and unobtrusive manner.
For example, a social breakdown which involves crowds of (pick one or more) hungry, angry, scared or dangerous people.
Or a martial law situation in which people are being directed to go to the designated "safe space", in the interest of "public safety"... You must decide if that is a direction which you actually should be going...
This article discusses some (by no means all) of the considerations you need to make about your bug-out.

Do your bug-out plans include the possible need to do so without drawing attention to you and your group/family?
