There's a Saturday in April when Saddle Brook changes over all at once — the salt washes off Market Street, the plow stakes come out of the ground, and every lawn in the township greens in the same week. From then on it's mowing on a rhythm, trimming tight to fences and foundations, edging along the walks, and clearing the yard of whatever winter left in it. When the cold circles back, the same driveways get plowed, the same walks shoveled and salted, the same properties made passable again. Saddle Brook is a township of close-set homes where a neat yard reads immediately from the sidewalk. Handling a place through both halves of the year means you learn its slope, its shade, and its one stubborn corner.
