The brick of the Historic Courthouse on the Lawrenceville square holds late light long after the streets have cooled, and that is the hour Sir Knight's Lawn Care works toward — engines off, edges still standing sharp. The work is plain and it is done well: mowing, edging, trimming close around posts, mailboxes and foundation lines, then a full blow-down so no clipping is left on the concrete. Gwinnett summers are humid and generous, and a yard left alone for two weeks will happily take itself back, so the rounds come steady. Come autumn the pin oaks and sweetgums let go all at once, and cleanups clear the beds and the fence corners where leaves like to gather. What a homeowner gets is a lawn that looks answered for — held to a line, week after week, on the streets running out from the old square.
