High summer on Highland Lake means docks, screen doors, and grass that puts on an inch every time it rains. Black Dog Enterprises LLC keeps those lawns and camp yards cut, trimmed and edged, with cleanups on either end of the season. Arriving at a cottage lawn gone shaggy and leaving it in clean parallel bands running down to the water's edge is worth the trip alone. Renters notice it. So do the owners who drive up from away wanting the place to look the way they remembered it. Bridgton in August is worth showing off, and a cut lawn is part of the showing.
