A cloud of toxic vapor from a derailed tank car forced at least 50,000 people to flee homes and businesses Tuesday in Minnesota and Wisconsin, creating traffic jams and leaving downtown Duluth deserted. "It's an absolute ghost town. It's eerie what's going on down there," Mayor Gary Doty said at an emergency command post outside the city. Residents were allowed to return after rain helped dissipate the toxic cloud.
