I have family up North - as in Canada. I'll be sending the family up there if I sense things getting really hairy. My family network is far greater and less dependent that my wife's family here. 7 hour drive to the border from here if highways/border open.
Other than that fly them out if possible. Fat chance if the S is hitting the F.
I think reality is that things would happen pretty quickly and most of would have to stay put. JMHO.
