It’s worse than that, actually. Her parents live in an obviously expensive home on a handful of acres with an expensive barn, horse facilities, a greenhouse, a massive pool/spa area...all right on a main road just 4 or 5 miles south of the interstate in a heavily (illegal) Hispanic area. They’re sitting ducks with no way whatsoever to defend their home and property. Plus, they’re both over 70. A generator would be the least of their problems.
Well in their shoes (assuming they don’t want to move) I would buy the generator and invite some well armed ex-military types to move in with me.
