Guy Debord outlines the psychogeographic practice of the dérive in his essay 'Theory of the Derive' which was first published in 1956 and reprinted in the Situationist International in 1958. The dérive, as Debord explains, is a theoretically charged stroll, usually in urban environments. Debord gives us the curious and amusing line: 'Wandering in open country is naturally depressing'. Perhaps at odds with many walking enthusiasts. This alone makes the practice of the dérive worth investigating further.
