The upper floors in most of the old houses in our area are finished in pine. The material is often covered over with carpet because it is a “soft wood“, not hardwood flooring. However, pine can have a beauty all its own, and we’re always barefoot by the time we get upstairs anyway:My mom tells an old story about her husband hopping across their old pine floors years ago on a pogo stick, leaving a trail of dot-dot-dot across the room.
