Diagonal and Duality

Note:
Well, the Lake Minnetonka “Ice out” is approaching and I will leave it to the authorities to declare the ice officially “out”. The small bays are starting to open, and I expect they will be free and clear soon. I saw a couple young boys pedaling their bicycles with fishing poles in hand.
My guess - a pretty standard April 3 weekend opening. I will wake to find Carson’s and Exelsior and Wayzata Bays have lost their darkened, slushy ice covering.
