"We can't forget, we can't not remember what occurred that day," said Portland Fire Chief Mike Myers.
It's been 15 years since September 11th, 2001. Terrorists flew planes into the World Trade Center killing thousands of people.
"For all of us here, 9/11 has become our day of infamy, the one we will never forget. The day we lived through, like Pearl Harbor was for our parents and grandparents, said Portland Commissioner Dan Saltzman.
On Sunday in Portland people stopped to remember.
"Please join me for a moment of reflection for the firefighters who gave their lives to save others," said Jason Lehman, the Vice President of the Portland Firefighters Association.
All over the area, people came together.
In Vancouver people gathered and so did folks up in Cowlitz County.
In Keizer, Fire Chief Jeff Cowan said a few words.
"We were attacked, we were at war, terror took on a new meaning," said Cowan.
Terror had a new meaning that the people at Ground Zero knew all too well. On Sunday firefighters from Tualatin Valley Fire and Rescue were there honoring the lives lost and the hundreds of first responders killed in the line of duty.
Back in Portland, a blood drive was also underway in memory of the victims of 9/11.
"Every drop you give will save a life," said Margo Benadom, a volunteer with the Red Cross.
Giving blood on 9/11 held special significance for some.
"Because of the loss of our civil servants and what happened in New York City," said Maryann Schell who showed up to donate blood.
She and others are determined to never forget the innocent lives lost and the first responders who gave their last breath to save others.
"Those 343 firefighters were going in as others were coming out, and everyday, today and forever, we will always go in when others are coming out," said Myers.
The Portland Firefighters Association also announced they, along with Portland Fire and Rescue as well as The David Campbell Memorial Association will be putting up a brand new memorial to honor Portland's firefighters.
It will be put up at Station 21 in Portland.
