3. What you are worried about is the windy, blustery, cold days with little snowfall. Especially after a warming trend. It turns everything to ice and in general it just sucks. Those are my most frequent ORD's (one run days) .
Overall the coverage is at it's best for the season in March. So it's a good month to bet on.
It's those icy days that make riding in the trees fun! You can always find some good snow in the trees.
