Went on Heath Bunting's psychogeographical walk in Nottingham, where we were trying to find a 'route' between places by linking their 'status'. He'd made a map of Nottingham based on things you had to provide to be able to access certain things (store cards, railcards, the lottery etc)
When we found a connection between places, we wrote it on the pavement (Able to provide proof of address etc) and as we went we discussed issues, such as identity and how it can be constructed.
