The Arkansas River valley lays out wide and level around Kibler, with the Boston Mountains standing blue along the north rim on a clear morning. CurbMasters LLC takes its name seriously: the line where grass meets concrete is the first thing anybody sees from the road, and it ought to be straight enough to sight down. Mowing, trimming, edging drives and walks, then blowing the clippings back onto the lawn instead of leaving them for the gutter — the whole visit is about how a place reads at a glance. Late spring is the hard-running stretch, when everything grows twice as fast as anybody planned for. A finished border holds its shape for days, and it is difficult not to look back at it on the way out.
