Olmsted handed Buffalo a park with a meadow at the heart of it, and ever since, this city has had opinions about grass. CGS Lawn and Co Inc keeps up its end of that on the streets around Delaware Park and well beyond, mowing to a clean height and running the edges so the line is honest. On Saturday mornings near Hoyt Lake the mowers start about when the rowers are already out on the water. Trimming, a blow-off of the drive, and cleanups in spring and fall complete the round. Nothing dramatic — just lawns that look cared for from the curb.
