The UK is criss-crossed with Think Air* Relays like this. Many, but not all, are close to transportation routes. Most are close, or perpendicular, to High Speed Cycle routes. Almost all of them are overground. People who live near the Thick Air Relays complain of various psycho-social effects including increased credulity and sloth, but they tend not to take serious action because, for reasons which are badly understood, property prices near the relays are wildly inflated compared to the local average.

*The Office of the Air Marshall has never really explained what Thick Air actually is. Many assume it’s just, basically, wind but the Thick Air scientists insist that it’s not. Neither, apparently, is it high pressure. It may be significant that the Air Marshall’s Office depends for its funding on the fact that the research and management of Thick Air are seen as national priorities. The reader can decide that for themselves.
