Down in Cotton Hollow, Roaring Brook runs loud past the old mill stones, and by mid-October the whole ravine has gone copper. RSK Tree Service keeps lawns in trim across the growing season — mowing, edging, trimming — and then takes on the long autumn job of clearing leaves off the grass before they mat. Once the brook ices at its margins, the same trucks turn to plowing driveways, opening walkways and treating them against the refreeze. Glastonbury weather does not negotiate, so the answer is simply showing up, storm after storm. The nearby towns fall inside the same day's loop.
