Blackhawks star Stan Mikita, who helped coach those game, also made an appearance.
A highlight Saturday was when an athlete carried the Olympic torch, which was subsequently lit by another athlete.
"It was fun. I lit it. I lit it by myself. I held on to it. I like it," said Special Olympics athlete Brett Bartz.
"It gives athletes with intellectual disabilities a chance to make friends, [to] compete. Their families get together, and they make a friendship and a bond. It's a great thing for everybody," said Shabbona Park Special Rec Instructor Lori Michalski.
Some of the athletes got a chance to shoot basketballs and show off their skills.
