Warren keeps early hours. Long before sunrise the streets fill with cars headed for plant gates, and a driveway buried under six inches of snow at four in the morning is a problem with a clock attached to it. McKissic's Lawn Care & Snow Removal, LLC works to that clock — plowing drives and lots, clearing walkways, laying salt so the first shift gets out on time. When the ground thaws, the same routes become mowing, trimming, edging and cleanups, the schedule loosening back into daylight. Warren runs on shift change, and so does this outfit.
