Saturday morning in Old Bridge sounds like sprinklers and a mower two streets over, and the light stays low enough for a while to watch the dew burn off. MJ's Lawn Care keeps that weekly rhythm going — cutting, trimming around trees and fences, edging the sidewalk seams until they read as one clean dark line. There is a particular satisfaction in finishing a yard before the day turns hot. The passes run one direction this week and the other the next, so the turf never learns to lean. A small thing done attentively, over and over, which is what a good lawn actually is.
