Saturday mornings near Loring Arena carry skate bags and coffee, and by the time the rink lets out the lawns along Fountain Street have been cut and swept. Martins K Landscape runs that kind of schedule — mowing, trimming, edging, spring and fall cleanups, mulch where the beds want it. The autumn stretch by Butterworth Park is all leaves, bagged and carted until the grass shows again. In winter the trucks carry plows instead of mowers, clearing driveways and walkways and treating steps before anybody heads out. Showing up is most of it.
