By late July the air over Thread Creek stays warm long after sunset, and fireflies come up out of the grass in Burton's back yards like the lawn is exhaling. Burton Lawn Care and Gardens takes its name from this city and works to earn it, mowing, trimming and keeping beds and borders tidy from the first green week to the last. Michigan summers swing between soaking storms and three dry weeks in a row, and a lawn only stays even if someone is paying attention to both. The pride is in small things: a mow line that runs true across a wide flat lot, a bed edge that holds, a yard that greets a family the same way every Friday. Nothing here is showy. It is simply a place kept well.
