They braved the cold water for this year's Polar Plunge Chicago, raising more than $1.5 million for Special Olympics Illinois.
Over 4,300 people plunged into the freezing Lake Michigan water at North Avenue Beach in Chicago, and they said it's worth it as they're changing the way people think about diversity.
It's called the polar plunge for a reason.
"Just thinking about helping others out," plunger Matt Buck said.
For Buck, he knows first-hand that the cause is worth getting a bit wet for.
"They're always making sure that i have everything I need as well," Buck said.
Diagnosed with autism Buck found opportunity to compete in the Special Olympics through Special Children's Charities, an organization raising millions for children to get a chance to live out their best lives.
"We do Special Olympics competitions all across the city, and live enrichment, so we offer things such as online cooking courses," Special Children's Charities executive director Amy Taylor said. "We do special rec and then we also do another partnership with second city, and we offer camps throughout the summer as well."

"I never thought he'd get those kinds of opportunities," Matt's mother Kathleen Buck said. "We do Special Olympics competitions all across the city, and live enrichment, so we offer things such as online cooking courses. We do special rec and then we also do another partnership with second city, and we offer camps throughout the summer as well."
The Bucks make the day a family affair. Kathleen says seeing the support from the city and elected officials, including Illinois Secretary of State Alexi Giannoulias, is a reminder that everyone deserves to find where they belong.
"They meet these guys and girls. They just have such a different take on life and finding their own, you know, what they're able to do, watching these athletes do what they can do," Kathleen said.
