Grass grows differently within a stone's throw of the Atlantic — salt in the wind, fog off Sandy Bay most mornings, thin soil over Rockport granite. Robs lawn care mows and trims straight through it, edging along the seawalls and short front yards of Pigeon Cove and the streets above Old Garden Beach. Spring cleanups clear a winter's worth of wrack and broken twigs; fall cleanups take the leaves before the first gale scatters them across the road. Mulch goes in dark around hydrangeas that turn blue here the way they do nowhere inland. It is a small town's worth of small lawns, each one cut so the lines run true to the street.
