Southwest of town Lonetree Reservoir goes hard and pale in midwinter, and the wind that crosses it reaches Berthoud with nothing softened out of it. L & M Enterprises plows into that — driveways, lots, drive aisles — then comes back for the walks and for whatever the wind has welded to the north side of the steps. Cold like that makes snow behave: light, dry, easy to move, and quick to blow back where it isn't wanted. So you plan the piles, watch which way the fetch runs, and give a place a second pass when the gusts have earned it. Done right, the ground stays clear long after the storm has gone off somewhere else.
