Philips-MCA has taken a different approach. Its aluminum-coated, plastic record, stamped from a master disc that has been etched by a laser beam, is covered with billions of microscopic pits. Variations in pit size encode the video and sound messages. For playback, a sharply focused beam from a low-power (one-thousandth of a watt) helium-neon laser scans the disc as it whirls around at 1,800 r.p.m. The laser beam flickers as it is reflected from the record's pocked surface, and the flickering is detected by a photosensitive cell, like that used in photographic...
...fouled streams and scarred mountainsides. By the mid-1940s, Butte's high-grade ore thinned out, forcing the company to increasingly undermine the town in its search for copper.

With the exception of one small bank building, no major construction has taken place in Butte since 1962. Arson has become common as people who are unable to sell their devalued buildings burn them for the insurance...
...called himself Thermidor and lucked into an exceptional lobster restaurant. Some of the CB messages are unembarrassedly commercial. A group of CB-assisted hookers plies one of the main highway approaches to Los Angeles ("This is Tender Love. I've got Lady Jane here ready for a pit stop...
