Fog sits on Thompson Lake most mornings until the sun climbs the far shore and lifts it off in one piece. Dyers Groundskeeping Services is out in that hour, mowing camp lawns and year-round yards while the grass is still cool and the water is flat. The rounds are steady and unhurried — mowing, trimming, edging, and the cleanups that bookend a Maine summer. What lasts is the edge along a walkway, sharp enough to read from the water, and turf that holds its stripe all week. Shoreline light in Otisfield shows everything, which is a fine reason to do it right.
