Saturday morning in Old Town Lafayette: alleys still cool, lilac hedges leaning over fences, somebody's radio going two houses down. Favela landscape services works these blocks with a mower and a trimmer, cutting, edging and blowing the walks until the small square yards look like they have been let out of a good haircut. The older lots here have odd corners — a shed, a stump, a fence line that wandered decades ago — and each one asks for its own approach. By noon the block smells of cut grass, the walks are swept, and the weekend can get on with itself.
