The other day I was walking into school and started to smell something. It was faint, hardly noticeable, and in the frenetic environment of a city easily missed. As I walked, I kept thinking to myself, "I know this smell." I couldn't quite figure it out. Then it hit me - the smell of grass. You know that smell you get it right as the grass is beginning to grow or shortly after you have mowed your lawn. Growing up that was the fragrance of Spring.
