Rensselaer stacks its back yards up the grade east of the river, short green terraces held apart by chain link and old lilac. Almost Free LLC works those yards on long June evenings, when the mowers run until the light goes soft behind the Helderbergs and the whole hillside smells like cut grass. Mowing, string-trimming along fences and foundations, edging the walks, keeping beds mulched and weeded — small work, repeated weekly, that adds up to a street you notice. Spring cleanups pull the winter grit and matted leaves off the turf; autumn cleanups take the maples down to open lawn before the ground locks up. It is one city lot at a time, and each leaves tidier than the mower found it.
