A little Mexican-food stand near the Terilingua "ghost town," some of which is still occupied and some of which consists of ruins of the Chisos quicksilver-mining company, which operated from 1905 into the early 1940s, and the residences of those who worked there. (Quicksilver is a now little-unused term for the liquid metal mercury.) A Web site for the town speaks of "scenic downtown Terlingua, Texas -- just a few exits past the end of the world." The dusty half-ghost, half-real town can be found on the road that connects Big Bend National Park with its state equivalent, Big Bend Ranch State Park, in southern Brewster County, Texas.
