A Saturday morning in Wauconda has a sound all its own — a mower two streets over, somebody's dog, the lake breeze working its way up toward Main. David's Landscaping moves through it one lawn at a time, laying stripes that run true and reaching the places a deck can't follow. Mowing, edging, trimming, cleanups: the list is short on purpose. What matters is the yard at the end of the hour, cut level and finished at the borders, ready for a weekend to happen on it.
