It's a day almost impossible to forget, but every year, Americans remember Sept. 11th.
For local firefighters, remembering their fellow Americans through a 343-mile relay race has been something they've done for the last seven years.
"The reason we do this is to remember the 343 firefighters who died trying to save the people that were in the twin towers," said Jeff Parsons, Idaho Falls Fire Captain. "They did save a lot of people, but a lot of them paid the ultimate price, and that's what we're here to remember today."
More than a decade later, 9/11 is still a reminder that life is short, but it's also a lesson for younger generations who have only heard of the attacks.
"I didn't have any loved ones in the building, but it still means a lot to me because I feel the sorrow for other people," said Natalie Marlow, a student.
Students at Holy Rosary in Idaho Falls invited members of the Idaho Falls Police Department, Idaho Falls Fire Department and Bonneville County Sheriff's Office to their school for a luncheon in their honor.
"A lot of these kids weren't even born when 9/11 happened and it gives us a feeling that all of those guys that lost their lives -- all of the firemen, law enforcement, they're never forgotten," said Bonneville County Sheriff Paul Wilde.
"The fire department and police department risk their lives for us and they'll never let us down," said Brigit Shannon, a student.
