A June morning in Calhoun starts cool and does not stay that way; by seven the dew is lifting and the bermuda is already reaching. Turf Masters of Calhoun works the grass itself — cutting at the right height, edging, trimming, keeping a lawn thick enough that it shades out its own trouble. Anyone who has watched a ball field get striped before a game knows what turf looks like when somebody pays attention to it, and a front yard is no different. Weekly mowing, edging, trimming and cleanup, kept up across Calhoun and the roads that run out from it, all season long. There is real pleasure in a clean stripe running to a sharp edge and stopping precisely where it should.
