Wind coming off the Hudson at Trevor Park has nothing to slow it but the Palisades on the far bank, and it arrives at the lawns above the museum with an opinion. Timan Landscaping works that exposed western side of the city — mowing and edging through the green months, trimming, mulching, and raking out at both ends of the year. When the wind turns cold it carries snow, and the same properties need plowing, shoveled walks and steps, and salt on the hidden ice at the bottom of a drive. The satisfaction is symmetrical: a lawn with a razor-straight border in August, a driveway opened clean before the first alarm goes off in January.
