Ron Reimink knew how uncomfortable and annoying swimmer’s itch could be. He spent much of his adult life trying to eradicate it in lakes across northern Michigan. Then one day, he realized he was completely wrong, writes Dan Wanschura in this story adapted from an Interlochen Public Radio podcast. Glen Lake is one of the most beautiful lakes in the world—clear turquoise-colored water, with Sleeping Bear Dunes National Lakeshore off in the distance. It was an ideal setting for Reimink’s summer job. One particularly beautiful day, Reimink, who’s a biologist, was walking around the lake, through the water, up and over docks, doing research on ducks. Then, a couple hours after he’d wrapped up for the day, he started to get this sensation in his legs. He looked down, and there were all these red spots popping up. Each one was around the size of a nickel. They started to itch like crazy. “And I literally scratched many of them until they bled,” Reimink said. “It was so intense.”
