It's the largest parade Rockford has ever put on, with more than one hundred groups represented, including local politicians, law enforcement, military servicemen and women and of course Elvis.
With hundreds of people lining the sides of the streets, not to mention the paraders themselves, Rockford police say security is number one on their minds.
"We always plan for crowd-control, we always plan and train for all the possibilities that could occur in regards to having that many people in one place," says Sergeant Dane Person.
This independence day, many parade-watchers are thinking about the security of our nation and the men and women fighting for it.
"They're out there fighting a war and with all the stuff that's going on, and hopefully one day we'll get it resolved," says parade watcher Armando Perez.
"My favorite thing is the U.S. Army because they fought for our country and they survived," adds Junior Robles.
Sergeant David Frye is one of those survivors. He served for more than a year in Afghanistan.
"I like the 4th of July because it helps people remember the origin of our country and the principles that our country was based on and one of those is freedom and independence day says it all," says Sgt. Frye.
Frye says he spends Independence Day thinking of his friends who are still overseas fighting for freedom and independence all over the world.
Sergeant Person says Rockford police didn't have any special security checkpoints set up Wednesday because it was mostly families parade watching and they weren't too worried about the crowd getting out of hand. That means police could focus on traffic control and keeping parade watchers out of harm's way.
Police also had an eye out for illegal fireworks and anyone drinking alcohol out on the streets. They say there were no serious problems to report.
