Take one Herrin street and watch it turn: April mud, June heat that makes a mower work for it, the amber weeks of fall, then a January morning with an inch of wet snow gone gray at the curb. Harmon Lawn Service is on that street for all of it — mowing, trimming and edging through the growing months, cleanups when leaves pile against the fence, then plowing, shoveling and salt on the walks once the cold settles over Williamson County. Winters this far south are unpredictable enough that a plow can sit idle for weeks and then earn its keep overnight. Both halves of the work end the same way: somebody steps out the door and the ground underfoot is right. That is the entire point of it.
