The first real mow of the year in Sanford comes late, after the low ground near the river has finally drained and the sand up on the ridges has warmed. Trevor's Land and Lawn L.L.C. works that calendar — spring cleanup, mowing and trimming all season, edging, mulch, and the long fall tidy when the leaves finally quit falling. Yards here run from small village lots off Saginaw Road to wide acreage where a mower gets to stretch out. Each one gets the same finish: even stripes, a true line where turf meets driveway, nothing left drifting across the concrete. Sanford is a small place, and small places notice.
