Letts Creek slips quietly through Chelsea, under the streets and past yards that have been mowed to the same width for generations. Brian's Service, LLC keeps that rhythm going through both halves of the year — mowing, trimming, edging and seasonal cleanups while things are growing, plowing, shoveling and salting once they are not. Village lots are close work: tight edges, gates to squeeze through, sidewalks that have to be passable by the time people walk down to Main Street. Finishing a whole block of them before the town is properly awake is the good part. The rest is showing up in whatever weather Washtenaw County decides to send.
