August in Cohoes sits heavy on Remsen Street. The brick holds the day's heat long after the sun drops behind the hill. Lawns want tending then — a careful cut, a trim along the fence line, the ragged corners squared away. A-J Lawn Sprinkler Co. Inc. keeps yards across the city green and orderly through that stretch, and keeps at it when cooler air finally comes down the Mohawk valley. There is real satisfaction in grass that stays kind underfoot all summer, right up to the last cleanup of the year.
