cruiser: a Machine People vehicle.
elbow root: ubiquitous Ringworld plant, a kind of natural fence.
daywalk: varies by species, but usually means a serious effort consistent with foraging and health. One daywalk for Machine People is about ten miles; for a Grass Giant, less, but they can keep it up forever. Gleaners can do one and a half Machine People daywalks for a couple of hours.
