Some lawns wake up loud, and that is rather the point. BAM! Green Lawn Care runs its mowing routes across Niagara in the early hours, when Hyde Park's long green shoulders are still silver with dew and the streets belong to nobody. Spring arrives late here and then all at once, grass going from grey to electric inside a single week, and the job is simply to keep pace with it. Stripes laid straight, the string trimmer taken to every fence line and hydrant, clippings blown off the walk before the truck door shuts. By five in the afternoon the block reads sharper than it did at eight in the morning, which is the whole reward.
