For your old man’s sake, have a plan. Have a go-bag, include SS card and birth certificate. Try and keep your vehicle 3/4 full. Chances are, you will have time to run to a safe state on one of the coasts. Pre-plan two routes, one for back roads and the other for highways and interstates, print it out. If you can, keep a minimum of $500 on hand and more like $1-2k.
I strongly recommend a handgun, take it to the range and practice enough to be proficient loading and shooting at 7 yards. A single woman is usually welcomed at ranges. Just don’t talk politics and if anyone asks, you’ve got a bad ex-husband. The more straight you appear, the easier it will be.
Sorry for the unsolicited advice/novel. Stay safe.
Dang, you’re in about as good a place as you can be then.
I hope I’m just an alarmist old fart. If so, my family ends up with a better life anyhow.
