In February the Hudson stacks plate ice against the dam at the north end of Troy and the cold settles into the valley like it owns the place. N.R.A Landscaping & Snow Removal runs the storms — plowing driveways and lots, shoveling walkways and steps, salting and sanding the ice that arrives on the back side of a thaw. Storms here rarely quit politely; they taper, refreeze and want a second pass. Coming back for that second pass is what turns a plowed drive into a genuinely clear one. Bare pavement before the workday is the standard.
