Wonewok Retreat Purchased
South Dakota businessman Dave Billion is the new owner of 3M’s former corporate retreat in northern Minnesota’s lakes country where Billion has vacationed for decades.
The Wonewok Conference Center on Big Mantrap Lake, just north of Park Rapids, Minn., is a 180-foot-long, pine log lodge with six cottages built in 1929. 3M purchased it in 1955 and operated the retreat for 70 years. It closed and went up for sale in 2023.
