A yard on the plains is defined by its lines: the fence, the shelterbelt of elms and junipers somebody planted a generation back, and the place where mowed grass gives way to open prairie. Mateo's Fence and Landscaping LLC works right up to those lines, mowing the open middle, trimming tight along posts and rails and tree trunks, edging where turf meets the drive, and clearing the yard out when the season turns. Midsummer mornings are the good part of it, cool for an hour or two before the heat settles in for the day. A lawn finished all the way to its own borders looks finished from the road. That is what people notice on the way past.
