February on the Scarborough side of Ossining specializes in a mean little trick: rain at dusk, a hard clearing overnight, and every sloped driveway glazed over by six. Salt and timing are the whole answer, and both have to arrive before anyone tries to walk out to the car. Clean Cut MS LLC handles that — plowing, shoveling the steps and paths, treating the ice on grades that don't forgive. When the ground softens the same attention goes into mowing, trimming and clearing the yard down to bare, tidy ground. Ossining and the river-facing streets nearby stay on the list right through the turn of the year.
