On a Sunday the Kane County Fairgrounds fill with tailgates and bargain hunters, and the rest of St. Charles goes about its quieter business of grass and weather. B & L Landscape Contractors LLC lives in that ordinary rhythm: mowing, trimming and edging through the green months, with a clearing-out at either end of them. Then January turns the alleys to freeze and thaw, and the work becomes snow plowing, shoveled walks and salt laid where the ice keeps coming back. A drive opened before the schools call is worth as much as any summer stripe. Both halves of the Fox Valley year, covered by the same crew.
