There is a week in April when Nebraska City turns loose all at once — the ballfields at Steinhart Park go from brown to green in about four days and every yard in town needs a haircut on the same Saturday. Grasskicking Lawns lives for that week. The first mow of the year is the loudest one, and the smell of it hangs over the whole neighborhood by noon. From there it settles into a steady beat of mowing, trimming and edging, plus the cleanup passes that keep a lawn honest through a hot Nebraska summer. The reward is simple and it never gets old: a yard someone is glad to walk out into barefoot.
