Nancy Well, 80, climbs out of the icy water with her daughter Susan Wells, right, after taking plunge for her eleventh consecutive year during the annual polar bear plunge Friday at Lake DeSmet. More than 150 people of various ages came to jump into the 38-degree water from an 10-by-30-foot hole cut from the ice surface. The Forister brothers have facilitated the plunge for the the past 17 years after taking it over from another group of individuals. “We just show up to create the hole and opportunity for others,” Rob Forister said. “It’s fun and we like doing it.” Justin Sheely / The Sheridan Press.
