Forest Avenue runs the length of the north shore, and Acevedo Landscaping knows it in both of its weathers. In the green half of the year it is mowing, edging, trimming, mulch and bed work, cleanups spring and fall on the tight Port Richmond lots where every foot of grass counts. In the cold half it is plowing, shoveling and salting driveways, walks and front steps before anyone goes looking for their keys. Two trades on one route, the same houses year after year — you come to know a yard better once you have seen it under six inches. The turn from one season to the other, sometime in November, is the part they look forward to.
