The flags were posted to remember the people who lost their lives in America's great tragedies on September 11th, 2001.
There are tags attached to each flagpole with the names of victims of that terrible day. I found the tag identifying a young woman from my home town. She was the daughter of one of my schoolmates from long ago. She was at work that day in one of the World Trade Center buildings.
It is a fitting tribute to those who lost their lives on that black day in history.
