The first real flakes usually find Lexington Avenue and the side streets off it after dark, small and dry and not looking like much. By morning Jeovannys Home Solutions has the walks open, the steps shoveled, the drives plowed and salted where the shade keeps the ice honest all day. The rest of the year those same addresses get mowed, trimmed, edged and mulched, with the cleanups that open and close the growing season. Village lots are tight — a fence here, a hydrant there, a gate that only swings one way — and doing them neatly is its own kind of skill. Mount Kisco comes first, then Bedford Hills, Pleasantville and Millwood.
