Out along the Buckingham and Addison roads the old stone walls run back into the trees, and by September the light arrives low and gold across the yards. P&C Landscaping is a Glastonbury landscaping outfit working those properties — lawn care and landscape work done at ground level, with a truck, a trailer and an eye for a finished line. There is an honest satisfaction in the moment the ramp comes up: beds clean, grass even, the yard quiet behind you. Autumn in this corner of town rewards that kind of attention.
