My fence is to keep deer and critters out of my vineyards and my livestock out of them also. Way too expensive for security.
I would think if the SHTF that there will be a very small window where travel will be safe for anyone. A group of trucks with armed men will taken a dim view of up here particularity if there are not women and children present. I would hate to be in the second group of thugs after the first tried to pillage.
God forbid any of this happens.
