Crusoe Lake sits flat and quiet at midday in July, and the creeks that feed it thread the low country north of the Montezuma marsh. Blue Water Lawn Care LLC keeps the lawns of that country cut and shaped — mowing, edging, trimming and the regular maintenance a hot, wet summer demands. Out here the properties are wide and the sky is wider, so a mowed line runs a long way before it ever turns. Holding that line straight to the far fence is a small craft with a visible answer.
