Greensboro, NC-Nearly 12 years after September 11th, 2001, it remains far too crystal clear to so many of us.
Hundreds of people were killed in New York, at the Pentagon and in Shanksville, Pennsylvania.
Among the victims were 343 firefighters and 72 police officers, who died in the attacks on the World Trade Center.
This weekend, the City of Greensboro is honoring those first responders with the third annual 9/11 Memorial Stair Climb.
On Saturday, firefighters with the Greensboro Fire Department, police officers with Greensboro PD, and regular citizens will accept the challenge.
They'll climb the Bellmeade Street Parking Deck nine times, which is the equivalent of 73 flights of stairs -- the highest floor New York City firefighters were able to reach on 9/11.
Chief Skip Nix, with the Greensboro Fire Department, said last year they had about 600 people participate in the Memorial Stair Climb. This year, they're hoping for 1,000 participants.
Nix said climbing the stairs in memory of the fallen is the least we can do.
It's free to participate on Saturday, but they're asking for donations, which will support the U.S. Marine Corps "Toys for Tots" Program.
Registration begins at 7:30 Saturday morning and the actual climb starts at 9 a.m.
The climb is at the Bellmeade Street Parking Deck, located at 220 North Greene in downtown Greensboro.
