YMMV / The High Window

• Aluminum Christmas Trees: As discussed in this article, the novel contains a puzzling-to-modern-readers reference to synthetic crowd noise at a Dodgers game broadcast on the radio, particularly given that the novel is set in California and was written well before the Dodgers left Brooklyn. As the article explains, between the 1920s and the 1950s there was an industry in re-creating baseball games for same-day delay broadcasts, and sportscasters (including future president Ronald Reagan) would mimic details such as crowd sounds and the noise of the bat in order to provide listeners with a realistic experience, when in fact they were reading the feed from a news ticker.
