Two names on the tailgate, a late-June afternoon, and a Mount Vernon block that needs cutting end to end. Michael & Tyler's Mowing Business goes house to house all summer — mowing, trimming around posts and playsets, sweeping the walks before moving on. There is chalk on the sidewalks and a hose running somewhere, and a mower is simply part of how the street sounds in July. They finish each yard the whole way, then load up and roll to the next one. A small outfit learns a town fast, one lawn at a time.
