Along Buffalo Avenue the driveways run long and straight down toward the water, and every winter here is a running bargain between thaw and freeze. DP Seal Coating takes the snow end of that bargain: plowing the drives out, cutting a path to the door, salting the low spots where meltwater gathers and turns hard overnight. There is a plain pleasure in blacktop reappearing — one clean rectangle in a white street. Storms come off the lake in bands and can drop more in an hour than the forecast admitted, so the route runs again. Niagara Falls winters are long, and a cleared driveway makes them noticeably shorter.
