This is the fourth year for the Paddleboard Specialists “Paddle for the Polar Bears” event, which raises funds for the Henry Vilas Zoo’s state-of-the-art Arctic Passage exhibit, a home for polar bears and seals. Hosted by Paddleboard Specialists and Wingra Boats, “Paddle for the Polar Bears” is all about having a good time while engaging in a fast-growing, simple-to-learn water sport.
