The sea is only a few towns east of Brockton, and in March you can feel it — a raw wind coming up off the bay that turns what should have been rain into something heavier by evening. Spinnaker Outdoor Services works both sides of that changeable month, plowing and shoveling through the last of the storms and then swinging into spring clearing and the first cuts of the year. Summer is mowing, trimming and clean lines on a weekly turn; winter is driveways and walks opened before the commute. Outdoor work here means reading the sky and being ready either way. The name fits the habit: catch the wind, keep moving.
