On a summer evening the wind comes up off Lewisville Lake, sets rigging chiming in the marinas, and carries a little relief into the neighborhoods back from the shore. Sandras landscape tends the yards where people step out to meet that breeze, mowing, trimming, shaping beds and holding the green tidy around patios and porches. Long North Texas summers ask a lot of a garden, and the job is not letting it slip: deadheading, weeding, cutting back whatever sprawls. When the water turns copper and the swallows give way to bats, the yard should feel like part of the evening rather than a chore waiting for the weekend. That is the quiet reward of tended earth in a lake town: more hours spent simply sitting in it.
