Lawns that run down to the water have their own rules — soft ground in the morning, wind off the lake by afternoon, and a shoreline edge that has to be trimmed by hand. Lake Mahopac Landscaping & Lawncare knows that ground well. Through the warm months it is mowing, trimming, mulching and the cleanups at either end of the season; once the lake starts skimming over, it is plowing, shoveling and salting those same driveways. There is real satisfaction in a lawn cut in clean lines above a gray November lake, and just as much in an open drive the morning after a storm. Mahopac and the lakeside streets around it are the whole of it.
