By November the oak leaves have gone leathery and hang on past every wind, and the shaded lanes on the north sides of the hills stop drying out until spring. Ironleaf Exterior Services works both ends of that year — mowing and edge work while the grass still grows, then plowing and clearing the drives once the ground turns hard. Black ice on a shaded curve is a different problem from a foot of powder, and it gets a different answer. The measure of a winter night is simple: the drive is open and the walk is walkable before anyone needs them. Ironleaf serves Wappinger and the towns surrounding it.
