Warren sits on heavy lake-plain clay, which means April comes slowly here — the low ground near Bear Creek stays soggy long after the air has warmed. RoLin Advanced Services waits for it, then works it: the spring cleanup that pulls winter's litter out of the beds and off the turf, followed by mowing, trimming and edging as the grass finds its stride. By May a yard that looked hopeless in March is dense and level and holding a line. Autumn brings the other half, leaves down and the lawn put away for the cold. It is ordinary work, and it is what makes a street look cared for.
