Murray Creek comes down off the hill and slips under the streets of Sayre, and the yards along its run are half slope, half flat — the kind of ground that asks something of a mower. Tree Service & Landscaping - R.C.I. handles them through the green months with mowing, trimming, edging and mulch work, and through the white ones with plowing and clearing. Night is when much of the winter work happens: headlights, blowing snow, a lot pushed open before the town has woken up. There is something steadying about coming down the hill at dawn and seeing every drive clear. That circuit runs across Sayre and the neighboring valley towns.
