Elgin's east side climbs away from the water in long slopes, and mowing a hill is a different craft than mowing a flat — you cut across it, you watch your footing, you keep the lines from wandering. Castrejon Lawn Care works those grades on Saturday mornings when the streets are quiet and the dew has just lifted. The reward is standing back at the sidewalk and seeing a slope striped evenly top to bottom, the trim line straight along the retaining wall, clippings swept off the steps. Small thing on paper, big difference to whoever lives there. Mowing, trimming and cleanups in Elgin, Bartlett, Streamwood and Hanover Park.
