Joyless people are always going on about how 'the' Wikipedia is scandalously unacademic and untrustworthy and all that, but the sooner you accept that some of it may not be strictly and accurately true, the sooner you can get down to the real business of appreciating its gloriously flawed nature.
Who wants stuffy academia, for example, when you can have lovely bits of user-generated bathos like this:
The name Falmouth comes from the river Fal, which is a Norse/Danish Viking name, strongly suggesting that the Danes used the deep water habour [sic] as a landing/resting place. During the Viking Age, the Danes did ally with the Britons of Cornwall, and the Vikings helped their Cornish allies by making pillaging raids on the South coast of Devon and Dorset, which was then controlled by the Saxons of Wessex, who were historically the enemies of both the Danes and the Britons.
Falmouth is the terminus of the A39, which passes in succession close to the neighbouring town of Penryn.
Which prompts the question: had the Vikings *known* about the A39, would they still have gone round the boaty way?
