The lots around McCullom Lake are modest ones — a strip of front yard, a back slope leaning toward the water, a hedge line to steer around. Roos Lawn Care takes those on week by week all through the growing season: mowing, string trimming along fences and posts, cutting the walk edge, then clearing the clippings before they mat down. Summers here are humid and generous, and a week of thunderstorms will let a yard get away from you entirely. There is a genuine pleasure in pulling up to a shaggy lawn on Saturday morning and leaving it tidy by noon. The same route carries out to the smaller towns north and west of McHenry.
