STOP, or not

   I don't know if there is a regulation for the height of  the placement of a STOP sign, but I think there should be.  I think the STOP sign in the village of Valley Falls at the north end of State Street is too high for it to be readily visible, at least from a regular passenger car.  A height of 5 feet would seem a standard installation; while I haven't measured the one in question, it appears to be about twice as high as it should be.  I think drivers unfamiliar with the terrain could easily miss seeing the sign altogether; it's way up there.  I hope "somebody doesn't get killed."
