Liberty Avenue carries the A train overhead through Ozone Park and Richmond Hill, and the shade beneath the el makes a strip of ground that grows on its own terms. DV & B Express Services covers both ends of the calendar there: mowing, edging, trimming and yard cleanups in the green months, then plowing, shoveling and salting once the pavement goes white. Storms rolling off the ocean reach this side of Queens before the rest of it, so the winter work starts early and stays quick. Speed sits in the name and in the habit — get in, clear it properly, leave a walk anybody can cross in ordinary shoes. July or January, the property should look like the day was handled.
