"The Night Climbers of Cambridge" was a book written under the pseudonym "Whipplesnaith" about nocturnal climbing on the colleges and town buildings of Cambridge, England, in the 1930s. The book remains popular among students. It is often credited with popularising and inspiring the first generation of urban exploring and night climbing. A new authorised edition of "The Night Climbers of Cambridge" () was published on 26 October 2007 by Oleander Press, Cambridge, to mark the 70th anniversary of the original edition. The new edition was updated and has proved popular among students and urban explorers. The story of the Austin Seven delivery van that ended up on the apex of the Senate House is not fictitious. The Caius College website recounts how, on 8 June 1958, this vehicle really did go "up in the world". The prank team comprised Peter Davey (organiser), Cyril Pritchett, David Fowler and 9 others. One story tells of a couple of students with a keen interest in climbing, who decided to scale the walls of King's College chapel after hours and place a roadcone (or similar object) atop one of the spires. On discovering the object the next morning, the college are said to have called in a building company to erect scaffolding in order to remove the offending object. However, the erection of the scaffolding could not be completed before dusk, and so the adventurous students ascended the chapel the next night and moved the roadcone to the opposite end of the chapel's roof, thus rendering the half-erect scaffolding useless. Parts of these attempts are described in "The Night Climbers of Cambridge". In 2002, a single toilet seat placed by a student on one of the spires remained there, eventually being retrieved by a steeplejack. In late November 2009 santa hats were placed on each of the four spires of the Chapel overnight. The College had these removed by a professional steeplejack at great expense. As the wealthiest of all Oxbridge colleges, Trinity College is naturally the subject of many rumours and popular urban legends. The college is sometimes suggested to be the second, third or fourth wealthiest landowner in the UK (or in England) — after the Crown Estate, the National Trust and the Church of England. (A variant of this legend is repeated in the Tom Sharpe novel "Porterhouse Blue".) In 2005, it was reported that the college takes in £20 million plus per year in rent from its properties. In comparison, the National Trust received about £42.6 million in rental income from its properties in 2005-06.
