There is quartz in the ledge at Old Mine Park, and the same stubborn rock runs under half of Trumbull's hills — which is why so many driveways here climb, bend, and hold ice long after the road is bare. Gillis Construction takes the snow off those: plowing, clearing the walkways, spreading salt where a slope would otherwise turn to glass by morning. Storms rarely arrive politely in this town; they come sideways at night and settle in over Chestnut Hill. The trucks go out anyway. By the time the sun clears the ridge, the drive is open and the day can start.
