Visiting the Chattanooga, TN, area with my daughter's softball team, we arrived early for pre-game warmup. I was pleased to find a walking trail encircling the park; a welcome opportunity for exercise before a day sitting on bleachers. A brisk walk through mist and chill. Fresh air. Morning sun. Mist. Ah, tranquility. But then, interrupting the natural scene: ball park lights. I remember why I'm here.
