Clear Blue Sky Grey Smoke

On 9/11 I was walking to radio shack in a strip mall four blocks west from my house the street has a gradual incline which was my way to get some exercise before work not knowing what was happening behind. When I arrived at the store everyone was looking at the TV .I walked back outside the way I came and realized they were looking at the billowing gray smoke from the World Trade Center rising in the Clear Blue Sky...A Sight I will take to my grave!!
