The 36th annual Jacksonport Polar Bear Club Plunge returned this year to the Lake Michigan lakefront.
With about 600 people invited, the event is billed as one of the largest plunges in the country.
It started in 1986.
The outside temperature was 18 degrees this time on New Year’s Day, but the people kept jumping into the lake.
The event raises money for the Jacksonport Fire Department.
Dozens more took the Polar Plunge down the lakefront In Milwaukee at Bradford Beach.
Onlookers say the participants were having fun when they jumped into the frigid waters, but they didn’t stay very long.
