As I was drifting off to sleep last night, I thought of something I hadn't mentioned - simple "disguises" - like Queen of Poop just mentioned. Baseball cap and even a bandana covering her hair underneath, sunglasses, and changing her coat, if he's familiar with what jacket she normally wears. Anything that might make it harder for him to tell who that person is ... it's an imposition, but better safe than sorry. Of course, if she's driving the same car to the same place at the same time, she needn;t bother, but if she's "out" with someone else, it cannot hurt.
