The train rumbled across old worn tracks breaking the not so silent sounds of cold city streets. A thunderous roar and screeching metal echoed off the walls of endless skyscrapers. I wanted to shield my frozen ears from the sound. I don’t know how people do it. To think every 15 or 25 minutes these trains crisscross through the city on elevated tracks brutally announcing their arrival only the way a speeding box of steel can. People on the streets walk briskly trying to get to their next destination…and trying to escape the cold. They don’t pay attention to the train overhead. This is just one of the sounds of the busy city to them. And it’s Chicago. People here are a little bit harder. They deal with extremes. 100 plus degree summers and subzero snowy winters. It’s about 18 degrees right now and it’s business as usual.
