Rob McKenna is an ordinary lorry driver who can never get away from rain, and he has a log-book showing that it has rained on him every day, anywhere that he has ever been, to prove it. He was described by the scientific community as a "Quasi Supernormal Incremental Precipitation Inducer". In the novel "So Long, and Thanks for All the Fish", Arthur suggests that he could show the diary to someone, which Rob does, making the media deem him a 'Rain God' (something which he actually is) for the clouds want "to be near him, to love him, to cherish him and to water him". This windfall gives him a lucrative career, taking money from resorts and similar places in exchange for not going there.
