The lanes toward Lattingtown narrow between old walls and hedgerows, and in late October they fill ankle-deep with leaves overnight. Gold Coast Property Maintenance, Inc. stays ahead of that with mowing while the grass still moves, leaf removal, bed clearing, edging and mulch as the year winds down. A property stripped clean of leaves in autumn looks like someone is paying attention, and paying attention is most of what upkeep is. The canopy on this shore drops in waves, so one lawn may need three passes before November is done. Glen Cove and the roads running out from it fill the calendar.
