I'm thinking of the old and perhaps sexist adage about men never wanting to ask for directions. Then I'm thinking about this early AM sighting. I can't imagine why someone would want to make up such a thing and put their real name out there (Mr. Davis) if it wasn't true. And I cannot imagine someone in their right mind doing this (this being pulling someone over to ask for directions to California - sounds like the beginnings of a sad country song).
So, that leaves me with four options (my MOO idle speculation only):
1. Mr. Davis made it up
2. Someone who lives in that area was trying to behave like Brian Laundrie (after all, the story is everywhere) for ***** and giggles.
3. It was actually Brian Laundrie and he's actually gone over the deep end.
4. It was actually Brian Laundrie and he was executing a carefully (rolling eyes) move in the same way that he hitchhiked in the Tetons. As someone else said, setting up an insanity plea of some sort.
