TRIP stands for Territories Reimagined: International Perspectives. Their website is here and it points towards some other tricksters who perhaps I may encounter on the Manchester leg of my walk, such as the Manchester Area Psychogeographic:
"MAP is a psychogeographic newsletter for Manchester and its surrounding area. Psychogeographic publications have poured out of London in recent years - we think it's time Manchester was looked at and recorded. Our aim is to bring to light the truth about Manchester that remains hidden by time, buried under layer upon layer of concrete, shoveled aside by banal culture. Our interests lie in the hidden history, the ulterior motive, and the suppressed geography that the consumerised city centre masks. To detect that geography we are prone to the use of disorientating and de-normalising methods in language and testimony."
Oh yes, their raison d'etre (as I think they say in Crumpsall) resonates quite deeply with me.
