North of the city the names still say paper — Parchment, laid out around its mill, the park up on the rise at Kindleberger. S & T Lawn Services Inc mows that stretch of the valley and the Kalamazoo yards below it: straight lines on small lots, careful work around porches and steps. On July evenings the crew finishes with the light still gold on the river bluffs and the last trimmer line wound in. Every visit is the same promise kept — mowed, trimmed, blown off the walk, done. Lawn care and yard maintenance for Kalamazoo and the towns along the river.
