Before the Hartsdale platform fills, the town belongs to the birds and the first mower of the day. MD Landscaping takes the early route — mowing, edging the walks, trimming close to porch skirts and hedges on streets where the houses sit near the road. By the time the trains have thinned out, whole blocks of Greenburgh have been cut and blown clean and nobody saw it happen. Summer here is humid and the grass runs; staying ahead of it means turning up the same day every week without fail. Coming home to a yard that was handled while you were out is a small kindness, repeated.
