Along the Hamburg Turnpike a Preakness year keeps two calendars, and Armando Group Landscape Services works them both. One runs green from the first April mowing to the last leaf hauled off in November, with clipping, edging and mulch laid dark around the beds. The other runs white and unpredictable, measured in plow passes, shoveled paths and the grit of de-icer underfoot. What links them is the same care about a finished line: the mower's last pass along a curb, and the plow's last pass along that same curb four months later. Neighbors here can tell which houses are minded simply by glancing down the street, in any month.
