Polar Plunges for Special Olympics are starting this week. This Friday folks in Medford will be jumping in frigid water to support the non-profit. Bend's Plunge won't take place until the end of February, but Sally Lynch with the Polar Plunge says the event actually started here in 2007: “The Bend event will be the fifth year. That's really the polar bear climate of the State. And after there was such a successful start, it moved on to Eugene, Corvallis and Medford.” The Polar Plunge will be at Riverbend Park Friday February 25th at 6:15 p.m. Organizers hope to have 700 participants this year.
