Chicago Heights keeps its alleys, and that means every property here has two faces: the front yard the block sees and the back one the alley knows. Rodriguez Best Yard tends both. The narrow parkway strip between sidewalk and curb gets the same attention as the open back lawn — mowed, trimmed, squared off at the concrete. Saturday mornings in this town sound like engines and sprinklers and somebody's radio through a screen door, and by noon a whole row of lawns can look like it agreed on something. Cleanups in April and again in November bracket the growing months on either side.
