Honestly, they don't even necessarily have to be in the woods. Just switching motels every few days. She's got her picture everywhere more than he does. He'd just have to change up his look, leave her in the car while he purchases a motel room for a couple days, and then when he gets the key they quickly usher her into the room and stay there. Time it right, and nobody would see her. Especially those motels where you can drive right up to the room doors. Comes with plumbing, toilet paper, water, shower, soap...a lot of them even have a few emergency feminine hygiene supplies in the bathroom under sink cabinets in case a guest starts theirs unexpectedly and doesn't have their own. They could do that for months unless they just so happen to run into a very sharp-eyed front desk person who also knows the case.
