I remember a talk with my father many years ago and it sort of relates to this topic.
We were having Big Time Civil Unrest( PC for RIOTS) very close by, ie under 10 mi.
I had just started backpacking a year or two before.
Well Dad said he was ready to send me camping if the Disturbance had continued another day. The local Authorities clamped down Hard and
reasonably fast I think (2day's trouble IIRC). In today's world I do not think
the disturbance would have been quelled as quickly, ie actions taken then are not currently P.C.
The short story was I would have gone camping Sis would have gone to a distant relative Dad and Mom would have stayed home to protect it until
the riot came much closer.
So Bug out to survive, kinda but survive what and for how long ?
Long term, it doesn't really work but you could be forced into it regardless.
