Some Theories

I can't really make a strong argument for any of these, but it's all I got.

  • A street worker is leaving his "signature" when he is on the crew to repave a street, much like signing your name in wet sidewalk pavement.
  • They are some kind of route marker for a route, where the directional-orientation and numbers tell you how many blocks to go and where to turn in order find the next set.
  • Some kind of dorky geocaching thing.
  • An advertisement for Domino's Pizza
  • stupid conceptual artwork.
