Late August evenings in Wing Park stretch out long and gold, and the grass there holds that light the way a well-cut lawn does. Perez & Sons Lawn Care Inc. chases the same look on the yards around it: mowed at an even height, trimmed tight to posts and hydrants, edged until the driveway has a real border again. The blower goes last, and the property gets handed back clean. It is ordinary work done with attention, week after week, from the first green in April to the last leaf run in November.
