There is a brisk little beat in the name Chop Chop Landscaping, and it suits the work: quick, clean passes across Mountain View lawns that leave nothing ragged behind. In the city's Eichler neighborhoods the houses turn their glass walls toward the back garden, which makes the front lawn half of the face a home shows the street. Afternoons, a dry wind riffles the grass along the parking strips, and by evening Castro Street fills with dinner crowds at its outdoor tables. Between those hours there is mowing to finish, edges to cut true against the curb and clippings to blow from the driveway. Through the long golden summer and the short wet winter, a yard kept on schedule looks the way these mid-century streets were meant to look: open, bright and unfussy.
