Come June the streets of Lake Hiawatha smell like cut grass from four in the afternoon onward — it is that kind of neighborhood, small lots kept close, hoses out, every yard visible from somebody else's porch. Grasso Lawn Service runs a route through those blocks: weekly mowing, trimming around posts and fences and mailboxes, crisp edging along walks and driveways, and cleanups when the season turns. The lots are modest, which means there is nowhere for a crooked line to hide and every finished lawn is a small, public piece of work. Long evenings, low sun straight down the streets, a fresh cut lying flat from curb to step — that is the good part. Then on to the next one.
