I had to think about this for a bit: here and there on the snow-covered fields at Edgewater Park were what looked like shadows created by patches of grass. They were only at the base of the relatively few pine trees.
My first thought was that the sun, very bright today, had melted the snow under these trees. Looking again I saw that the clear areas were those that were protected by the trees, not exposed to the sun.
So the "shadow" must have been created when the snow fell, blowing in from the East and leaving clear areas where the tree's branches and needles kept if from getting through. Never noticed that before.
I guess this is an anti-Hillary sign, although for die-hard Bill Clinton folks who welcome the thought that he'd be almost back in office, I guess it could be a good thing.
Seen on Woodbine near Fulton, one of the few presidential campaign signs out in the neighborhood. With a primary only eight days away that's kind of strange.
