In May the ospreys are back on their poles out toward Sandy Point and West Haven has its windows open again. S.GREEN LANDSCAPING SERVICE gets going then, with weekly mowing, edging the concrete clean, trimming the corners, laying mulch into beds gone pale over the winter.

Cleanups top and tail the season, once in spring and again after the last leaves come down. The satisfaction of it is uncomplicated: a lawn that looks like somebody paid attention.
