The occasion wasn't lost on Matt Meadors, a lover of history.
"I'm really excited, it's gonna be a lot of fun," said Meadors, a Cabot junior. "It's definitely great to be a part of something this big. And I'm really excited."
"I don't even know, I can't even imagine what it's going to feel like," added sophomore Kaley Elmore.
Hundreds of thousands lined up to see the participating bands. It's the third time Cabot's had the privilege of marching, and teachers say the moment is special every time.
"And when you turn the corner on Constitution Avenue and there's 250,000 people packed into the space of a mile, chill-bumps! That's all I can say is it's a chill-bump moment, it lasts for a mile, and when it's over you say I can't believe I just did that," added band director Joe Trusty.
It was the first time in Washington D.C. for most of the band, and they were excited to to be in the nation's capital for Independence Day. For senior Megan Hefner, who's headed to the University of Arkansas to study music, it's a moment she wants to keep forever.
"I'm never going to be able to do this again, so just enjoy it while we're here," said Hefner.
And for one day, at least, the sounds of Arkansas were heard by a nation.
