The interstate never really stops humming past McDonough, and the town has grown up around those exits — new streets, new lots, more grass than there used to be. FastLine Lawn Care runs a weekday route through it, first mower down not long after sunrise, working steady toward Stockbridge and Locust Grove before the afternoon heat sets in. Mowing, edging, trimming, blowdowns — nothing fancy, just finished and finished on time. People notice when the crew arrives the day it said it would and the lawn looks cut rather than shortened. That rhythm is the service.
