Must return?

       I went out to Bunker's Hill for some Cow-juice & Hen-fruit.  On the return run I stopped at a place I've stopped before; to take a shot of a "Plastic Field."  Prior to it becoming a Maize field.  On the few steps back to the Car I noticed this.  
       On the side facing us, I could see "WTON"; with, I'm guessing, room for an "NE" preceding it.  On the other side - all I can say, with certainty is there's something carved.  The age old chant?  "We shall see."
