Ice Thickness

Drilled the hole like I said I would,21.5" and worst part is it's still blue ice.A group of 6 ice boats went for a picnic yesterday afternoon South and West of Crescent Island.one of the couples lives in Tranquil Channel area and they boated to Kennedy island,picked up by ice boat and transported to picnic site.we had a bright sunny afternoon with only a light N breeze and a high of 10c.This morning the open water out front skinned over,2days ago when this happened it took till 13:30 that afternoon for the fresh ice to disappear! This morning,s forecast has a windchill,and 40% chance of flurries?Not exactly what you folks that are packing for th May Long weekend want to hear.It is still a little early yet but we will be telling our family to have a back up plan for long weekend.In our travels yesterday we crossed several holes 2-10' diameter ,also several cracks that were wet but no open water in them yet.The ice on the South side of the Barriers appears softer than the ice on the North side.The closest ice out prediction I can give is when we get the phone call that ice is out on Laurenson Lake ours is gone 7days later.
