Fog lifts off the Mississippi and moves up over the levee, and for an hour Venice is quiet and gray before the day turns bright. Straight Edge Landscaping is out in it — mowing lawns, running the trimmer tight to porch posts and fence corners, cutting the borders back in along the concrete, and carrying off the yard waste. The name is a promise about the finish: a lawn squared to its walk, with no ragged fringe left at the fence. Bottomland soil holds moisture long after a storm, so the passes get planned to keep the turf from tearing. By late day the mowed grass smells sweet in the heat, and the block looks like someone paid attention.
