One thing we read everyday and dont even know about it. Without these signs we more than likely couldnt get around town and know where we are going. I have been lost before driving in unfamiliar places and these road signs helped me out a lot.
Would you tell me, please, which way I ought to go from here? - That depends a good deal on where you want to get to. - I don't much care where - Then it doesn't matter which way you go. Lewis Carroll, Alice in Wonderland.
