Levings Lake sits quiet on the west side, and the streets around Rockton Avenue run down toward it under big shade trees. Evans Lawn and Snow keeps those yards mowed, trimmed and edged through the long green stretch of a northern Illinois summer, with cleanups when the season opens and again when it closes. February turns the same route into plow work — driveways cut open, walks cleared, salt on the slick patch by the steps. The pleasure is in the before and after: a wall of snow at eight o'clock, an empty driveway at nine. Same houses, same care, different weather.
