Firefighters taking part in the fifth annual North Dakota 9/11 Memorial Stair Climb at the state Capitol in Bismarck on Friday. More than 110 firefighters, first responders and volunteer participants from across the state walked up 17 flights in the Capitol tower seven times to honor the fallen the firefighters killed in the Twin Tower terrorist attacks in 2001. In all the annual event has raised more than $30,000 to support the National Fallen Firefighters Foundation providing counseling services for families of local fallen firefighters and the Fire Department of New York.
