When I lived in the Keweenaw March was such a great cross country ski month. I considered March a full winter month too. It was April when I was done with winter. You would start losing all the snow and then that April some would come and put 1/2 of it back on the ground. I recall May10th, 1990 snow that cancelled Summer classes at NMU (first time ever NMU cancelled summer classes due to snow).
