 Duluth City Councilors will debate the proposal in two weeks. Authorities say a 26-year-old man from Northfield drowned in a lake in the southern Twin Cities metro last weekend after getting knocked off an inflatable device by the wake from a boat. The Dakota County Sheriff's Office says it happened at about 5.30 p.m. Saturday on Lake Marion at Antlers Park in Lakeville. This is NPR News.
