Living in a rural area, with our own well and septic plus our normal food supply stock, I’m thinking that our best chance, should it make it here, is to lock the door and stay home for as long as it takes.
Grab an old grocery list and check it for things you might normally pick up that will keep and make sure your supplies are up to snuff...things like toilet paper, hygiene supplies, soap, laundry detergent, and some extra fuel are good, too.
If you do plan to sit a spell, remember to fire up the vehicles once a week and run them for a few minutes to keep the batteries topped off and the seals limber. Listen well for anyone around first...
