Young couple goes on van tour of US, boy comes back with van - no girl

Who calls 911 because someone is knocking on their door? Shouldn’t they welcome any help in finding their son? I know Dog is here for the exposure, but he is fairly experienced in tracking people that don’t want to be found.

Maybe they don't know who the dog is?




If you didn't know who this guy was, would you answer the door, if he knocked?
