Olean keeps two calendars, and Armstrong Lawn and Landscaping keeps both of them. From the thaw that swells Olean Creek down to where it meets the Allegheny, the work is mowing, trimming, edging and hauling off everything winter left tangled in the beds. Then the light shortens, and the same trucks go back out with plows and spreaders to open driveways, aprons and walks. Watching a shaggy yard resolve into even bands of green is its own reward; so is a cleared drive at the end of a long night. Lawn care and snow removal for Olean, Allegany and the valley between them.
