There is a stretch of July in the Oneida County hills when grass simply refuses to quit — warm nights, afternoon thunder rolling off the plateau, two inches of growth between one visit and the next. Grass Assassins LLC exists for that stretch, mowing and trimming Remsen yards on a schedule tight enough to keep the upper hand. The work is quick and it is exact: one height across the whole lawn, tight lines around the posts and the porch skirt, walkways cleared before the truck pulls away. Spring and fall the same yards are raked out and edged so the season opens and closes square. Nothing in these hills stays tame on its own.
