In January the Tybee pier belongs to pelicans and a few walkers in jackets, and the island's streets are as still as they ever get. SMC Lawn Care likes that stretch of the year for its own reasons — cleanups, cutting back, edges redrawn, beds cleared before the green rush of March. Then spring lands all at once, and mowing, trimming and blowing run weekly straight through a long, humid summer. Sandy soil and salt wind keep island turf honest, and steady cutting is what keeps it even. Come home to fresh lines in the lawn and the whole lot looks bigger than it did.
