The day the twin towers in New York city were attacked by terrorists in airplanes and brought down.
Nearly 3,000 people were killed.
Tomorrow is the anniversary of that horrible day but those who died are not forgotten.
On the grassy lawn between the Prescott Valley Civic Center and the Police Station, three thousand flags are flying.
It is called the Prescott Valley Healing Field of Northern Arizona.
Each flagpole has a card attached with the name of one of the victims.
Only one came from my home state of North Dakota.
This is her card.
I never knew Ann but she came from my hometown and was the daughter of someone I grew up with.
I have sought out her card before and spent a moment at her flag.
You may have noticed the boots at the base of some of the flags. They are placed to remember firemen who died when the towers collapsed.
The display is put up by volunteers every year to allow people to commemorate the lives lost in the tragedy.
As President Roosevelt said of December 7th, 1941 when Japanese planes attacked Pearl Harbor, "it was a day that shall live in infamy."
September 11th, 2001 was another such day.
