   Hey, just as an aside.   
   Do you know WHY they are the distinctive shape they are?   
      
   The reason, I read somewhere, I think in the 1976 MUTCD, is   
   that the OTHER driver (the one who does *not* have a STOP sign),   
   can *recognize* that there is a stop sign, merely from the back   
   of the sign.   
      
   That is, the octagonal and triangular shapes tell the OTHER   
   driver that you have the respective signage applying to you.   
      
   That's pretty neat!
