If the gal is truly a liberal, when you bring her in to save her butt, she will take the first opportunity to rat you out to the ‘collective’.
She already knows her dad is a ‘prepper’. If she was going to turn you in to Big Brother, she could do that from anywhere.
Think about it.
I'm not sure how that will happen unless they come with her. They aren't welcome and there will be no doubt in anybody's minds about that. If anybody wants to force the issue, it will get ugly fast and most Liberals aren't into "ugly" if it means them on the receiving end.
In a SHTF scenario, power and cell phones will be down and there will be little communication or free movement. She will have no transportation available anyhow and it's a bit of a walk to town much less to any "friends". My rules also include remaining in place and not wandering around making yourself a target of opportunity. Prepare for a long stay, plenty of guard duty, hard work, diet discipline, and no iPods or TV.
