From the bluff at Riverview Park the sun drops behind the Missouri shore and lays a long orange line on the water, Quincy's own nightly event, free to anyone who walks up. Grass Doctors mows and trims lawns through the months that make that walk pleasant, then plows drives and clears walks through the months that don't. Winter mornings up on the bluff come in cold and blue, and the work begins before the sky does. A cleared drive and a cut lawn are small things that quietly decide how a day goes. The service runs across Quincy and the towns nearby.
