This weekend, thousands of people across the country took a swim at the same time, without bathing suits.
Michigan Radio’s Lindsey Smith went to Union City, near Battle Creek, to witness part of the world record skinny dip attempt.
She filed this audio postcard.
More than 200 people skinny dipped at Turtle Lake on Saturday.
It’ll take about a week to determine if they helped break the old record of 13,648 people.
