Ice Yacht sailors from all over the country converged on Lake Minnewaska this weekend to man their ice yachts and take advantage of good ice conditions for sailing.  The weather cooperated on Friday with winds at about 10-15 miles-per-hour and sunny, warm temperatures.   The warm weather continued on Saturday, albeit with a bit less wind, and even more ice yachts could be seen sailing on Lake Minnewaska from the Starbuck Beach area.
