I just conferred with my Mom ... who bought in '56 ... they always went to the Lake for the 24th long weekend. She cannont recall ever going on that weekend and having ice on the lake. She does recall going up a week before and as they went across it was like going thru a big slushy, but that was gone by the afternoon. So, since the weekend is actually on the 20th ... I'm calling the 18th .....
