It was a brisk -17 C on Saturday morning for the fourth annual Polar Plunge in support of Special Olympics Ontario.
About 100 people gathered to take a dip in the frigid waters of Ramsey Lake.
One of those was Sudbury.com reporter Darren MacDonald. While he didn't take the plunge himself, he did capture some video of those who were brave enough to make a splash.
Take a look...and try to think warm thoughts.
