Out on the east side the land tips gently toward Lake Massabesic, and the lawns there hold their green a little longer for the water and the shade. Beaver Lawn Care LLC mows those yards on a steady rotation, edges the drives and walks, and keeps the trimmer moving around fence posts and mailbox stones. Early summer mornings smell like cut grass and pond air, and by the time the mower comes off the trailer the dew is only just burning out of the low ground near Cohas Brook. Fall is a different job entirely — leaves off the beds, off the turf, off the whole shape of the season — and it ends with a yard that looks put to bed on purpose. It's plain work done thoroughly, and a tidy lawn on a Friday afternoon is its own kind of proof.
