Mid-June in Mystic, the bascule bridge goes up on the half hour, traffic stacks along the river, and the town smells like water and cut grass in equal measure. Mystic Lawn Care runs its routes around all of that — early cuts before the day fills up, trim lines around fences and mailboxes, edges taken back off the sidewalk where summer growth has crept. Spring opens the season with a cleanup and beds freshened with mulch; October closes it with leaves off the lawn and a final low cut. Weekly mowing sounds simple until you see a yard that has had it done right for a whole summer. That is the version this town gets.
