Went up to west Lake Okoboji last night to check the ice. A local sailor sailed late Sunday and called down Monday and said the ice was great. He was right! 4-5 inches of clear hard ice. It is a piece that is 1 X 3 miles in size. We checked it at Gull Piont State Park. We are going to sail Thur. or Fri. before the next storm hits on Sat. Flirt II
