A pair of Burlington Northern EMD SD40-2s power a westbound BN stack train past the entrance to the Stonefield Historic Site at Cassville, Wisconsin, on May 24, 1992. In an idyllic setting along the Mississippi River, Stonefield is the 2,000-acre estate of Wisconsin’s first governor, Nelson Dewey, that features over 30 buildings in a beautiful setting that celebrates Wisconsin’s rich agricultural heritage for everyone to enjoy.
