Today my Mom was driving us down to the beach (I know, it's a little cold but it is nice to walk along the boardwalk when no one else is around). We saw three identical white vans in a row, maintaining distance and driving the same speed. Not like soccer-mom minivans either, but the larger cargo vans with no windows except in the cab and small ones on the back doors.
She made me get down in my seat when she passed them. She said she couldn't see much, except that each van had a male driver and passenger wearing what looked like dark blue jackets and blue ball caps. Every one she could see was wearing sunglasses as well, even though it was kind of a gray day.
She said the driver of the lead car is the only one that looked over at her. She wasn't sure, but she thought he might have given her a little nod.
She didn't want to go to the beach after that, but I insisted. We actually had a pretty good time. The seagulls don't care that I'm dead.
