There's a place I've been looking at for a while. Just gonna throw it out there and see what y'all think.
Go here and click on the person icon at the upper right, then type a certain surname into the search box (no first names!):

If you typed in the correct name, you'll find a 50-acre parcel of mostly wooded land out past Conway, just north of Highway 22. Looking at the shape of that parcel and matching it to satellite images, it does not appear that anyone lives on that land. Nearby, but not on it.
I wonder how familiar TM/SM are with that land. And I wonder if it's been searched.
