Hundreds of people took part in a movement called "The Great American Clean Up."
They rolled up their sleeves and picked up anything, from bottles to wrappers and put them in the trash.
Volunteers like Gary Baner say if trash isn't picked up in the city, it can pollute other outlying areas harming plants and animals.
So it's important to pitch in.
"We see cups and bags and stuff blowing across the countryside. Getting captured by the fences and it's just an eye sore out there, out in the country," said Baner. "I'm not saying it starts here, but people need to recognize it's not just in the city. It's everywhere."
This is the 14th year for clean up.
Last year volunteers collected 160,000 pounds of litter.
