The ferries between Bayfield and Madeline Island stopped running last week and until the ice is thick enough to drive on, the transportation across Lake Superior is provided by wind sleds. Wind sleds are powered by two big fans to propel across the ice. This 24 seat wind sled, Ice Angel IV, carries supplies and people back and forth from the island. At least there is some wind protection but I imagine it is a cold two mile ride in the sub-zero temperatures.
