Southeast Michigan skies belong to the water around them — flat gray lids in March, towering white in July, and a light off the lakes that can make a mown lawn look lit from underneath. Great Lakes Services works under all of it in Ypsilanti Charter Township: mowing on a weekly rhythm, edging, string trimming, and the cleanup passes that bookend the season. Grass here comes on hard in spring, sulks through August heat, then greens up again in September. Reading that arc is most of the job. The rest is showing up with sharp blades.
