Took a trip to Idaho over Labor Day weekend. In the ghost town of Custer, a ways north of Stanley, one of the remaining houses had walls lined with layers of newspaper — part insulation, part decoration. Someone lived in the house for a long time without upgrading, because the newspaper layers were every 20 years or so. You could see a layer from the early 1950s over a layer from the late 1930s and a layer beneath that that wasn't visibly dated. However, the town itself started to close down much earlier. Mining (the reason a town of a couple hundred popped up in a remote valley in the first place) stopped much earlier.
