The land around Lake Isle folds and dips, and Eastchester's yards go with it — a rise here, a hollow there, hardly a flat rectangle on the whole block. Hidden Valley Landscaping mows those grades the way they ought to be mowed, following the contour rather than fighting it, so the cut looks unbroken from the top of the drive. Trimming reaches the awkward places: the base of a stone step, the slope behind a garage, the far side of a hedge nobody can see from the road. In spring and again in fall, cleanups clear what collects down in the low spots. Uneven ground, even grass — that is the trick here, and pulling it off never gets old.
