We used to do a lot of urban exploration here in London (without all that infantile mystical hippy bollox). Disused King William st tube tunnel under the Thames with original careless-talk-costs-lives WWII posters, disused Caledonian rd tube station, deep level WWII underground shelters at Goodge St and Clapham. Much harder these days cos of bastard CCTV everywhere and ridiculous terrorism paranoia. They'd prob send you to Guantanamo. I recently climbed up onto and explored the highe level disused railway line running north from Broad street alongside Kingsland rd. I've heaps of pics somewhere of all these exploits though it'd take me ages to find them.

i erally od apprecaite the idea and the attempt but that video is really poor and not worth downloading

I clicked the link to the psychogeography video but my media player couldn't display the film, it said there was a comopent missing or somesuch- any chance it could be posted up again in a different format, I'd like to see the video as I was one of those on the walk and didn't really have a clue wot was going on...
