Post Avenue wakes early — shutters up, coffee out, the sidewalk still cool — and the lawns behind it wake with it. Augusta Lawn Care of Westbury works those front yards where the grass runs right up to the walk and every edge is on display from the street. Mowing in tidy passes, trimming the strip along the fence, blowing the clippings back off the concrete so the line between green and gray is a line again. In June the cut is weekly and the smell of it follows the truck down the block. It is small, ordinary work, and it makes a whole street look cared for.
