Downtown on Wilcox Street the January cold gets into the old stone storefronts and stays there, and the sidewalks on the shaded side hold their glaze until noon. Segura's Stone LLC handles the snow side of that season — shoveling and clearing walks, plowing drives and lots, breaking up the ice at thresholds and curb cuts where a person actually puts a foot down. The work happens in the blue hour before Castle Rock starts moving, and it is finished when there is nothing left to see but wet pavement. Coverage takes in Castle Rock and the nearby towns of Sedalia, Castle Pines and Franktown.
