Every property line in Wisconsin traces back to a survey point set just outside Hazel Green — the Point of Beginning, where the measuring of the whole state started. Sunny Valley Landscaping likes working in a town with that kind of claim on order. Their trade is lawns: mowed, trimmed, edged, and cleaned up through a growing season that fills these driftless valleys with light from May to October. Mornings they follow the sun down the hollows; afternoons they finish on the high ground where the hills run off toward three states. A straight edge on a green lawn, in the place where straight lines began — there are worse ways to spend a summer.
