Kenosha's Civil War Museum, 5400 1st Ave., will present a detailed look at slavery and how those in the Upper Midwest fought against it in the 19th century. The program comes in the form of an after-hours museum tour featuring such artifacts as a slave bill of sale, a slave collar and other objects in the museum's collection. Curator Doug Damman will host the tour, which spotlights the Underground Railroad as it led through Wisconsin and other nearby stop-overs.
