Mirror Lake holds the mountains upside down on a calm July morning, and North Elba's summer, brief as it is, turns everything an intense green. PLACID TURF PRO LLC works that window closely — mowing on a regular cycle, string trimming around rock outcrop and foundation, edging drives and walkways, and clearing clippings off the pavement. A spring cleanup takes the winter sand and debris off the grass; the autumn one gathers leaves and needles before the first real cold. Up here a lawn has to earn its keep in a hurry, and a clean cut against birch and balsam looks like the season doing its best. North Elba and Lake Placid, straight through the green months.
